Description

Multi-point micro-force sensor, in-body type muscle force detection equipment and application thereof

Technical Field

The invention relates to the field of piezoelectric film sensors, and further relates to a multipoint micro force sensor, an in-body type muscle force detection device and application thereof.

Background

The piezoelectric film sensor, also called a pressure film sensor or a film pressure sensor, is used as a dynamic strain sensor capable of detecting dynamic stress, and is very suitable for detecting vital signals on the surface of human skin or implanted in human body. While some piezoelectric thin film elements are sensitive to detecting the pulse beat of the human body through the outer sleeve. Typical piezoelectric materials are sensitive to pressure, but for piezoelectric films, a very large stress is created in the transverse direction when a small force is applied in the longitudinal direction, and much less if the same force is applied to a large area of the film. Thus, piezoelectric thin film sensors are very sensitive to dynamic stress, with a typical sensitivity value of 10-15 mV/microstrain (parts per million change in length) for 28 μm thick PVDF.

Therefore, the piezoelectric film sensor is generally applied to medical devices such as a stethoscope, a heartbeat detection device, a respiration monitor, an in-body muscle strength detection device, or a kegel medical exercise device, which can effectively detect human motion characteristics such as heartbeat, respiration, targeted exercise feedback, muscle recovery strength, postoperative rehabilitation index, and the like.

For some in-body muscle strength detection devices, such as a kegel trainer or a male prostate rehabilitation device, the in-body muscle strength detection device needs to be placed in a cavity of a human body, such as a female genital tract cavity, a pelvic cavity, a urethra cavity or an anus cavity or a male urethra cavity, an anus cavity, a pelvic cavity and the like, wherein the piezoelectric film sensor is arranged on the surface of the in-body muscle strength detection device, and in operation, the piezoelectric film sensor can directly or indirectly receive acting force applied by a pelvic floor muscle group or a sphincter muscle group or a pubic coccyx muscle group of a male or a female, and convert the acting force into a series of electric signals to be transmitted to a user side, so that the user or doctor can acquire feedback results of the massage, training or rehabilitation process, and the rehabilitation training or the massage schedule of the user is facilitated.

In general, the piezoelectric film sensor is formed by connecting a plurality of micro force sensing units in series or in parallel, each micro force sensing unit has a certain detection area or area, and the piezoelectric film units are mutually connected in series or in parallel to form an integral piezoelectric film sensor, wherein the larger the number of the micro force sensing units is, the higher the detection accuracy of the piezoelectric film sensor is. However, in the present structure, the plurality of micro force sensitive detecting units are generally arranged on the surface of the detecting device in a transverse direction or a longitudinal direction or a unidirectional direction, that is, each of the detecting regions is arranged in a transverse direction or a longitudinal direction or a unidirectional direction, but since the detecting device has a certain size, that is, the sum of the widths of each of the micro force sensitive detecting units is smaller than the width of the working region of the surface of the detecting device, the number of the piezoelectric thin film units is limited by the width of the working region of the detecting device, and further more piezoelectric thin film units cannot be arranged, that is, the micro force sensitive detecting units can only be arranged in the same direction in the effective working region of the detecting device, so that the detecting accuracy is low.

It can be seen that each of the sub-detection areas corresponds to one of the micro-force-sensitive detection units, so that the detection value of each of the sub-detection areas is single, and the accurate contrast is too low, so that the detection accuracy is low. In addition, when any one of the micro force sensitive detection units is damaged, correspondingly, the detection area cannot be continuously detected and partial data is lost, so that an algorithm data chain of the piezoelectric film sensor is interrupted or wrong, and the micro force sensitive detection unit cannot be continuously used, and even diagnosis of a doctor or exercise or massage plan of a user is misled.

In addition, when the detection device is provided with the micro force sensitive detection units, each piezoelectric film unit needs to be supported by the shell of the detection device to form a stable working area so as to ensure the sensitivity and safety of the sensing area. Correspondingly, each micro force-sensitive detection unit is installed at intervals, so that the working area of the surface of the detection equipment is wasted, and further more micro force-sensitive detection units cannot be installed, so that the sensing accuracy cannot be improved.

Generally, the piezoelectric thin film sensor is mounted on a surface layer of the inspection apparatus, wherein a sensing element of the piezoelectric thin film sensor is disposed on a surface of the inspection apparatus to receive and sense an external force applied to the surface of the inspection apparatus. When the external force is applied to the piezoelectric thin film sensor or the piezoelectric thin film sensor is stressed for a long time, the detection sensitivity of the detection element of the piezoelectric thin film sensor may be reduced, even damaged, and the service life is reduced.

Particularly, the muscles corresponding to the human body cavity, such as the muscle tissue of the pelvic floor muscle, are complex, the pressure generated by the muscles at certain position points is tiny, which is generally called as muscle tiny force, and because the pressure of the muscle tiny force is small, the electric signal detected and output by the existing detection equipment is weak, and even is difficult to output as the electric signal, so that the output of the detection signal of part or all of the muscle tiny force is lost, the sensitivity of the detection result is low, and the change of the tiny force of certain muscles of the pelvic floor muscle cannot be obtained more carefully, so that the detection result is unreliable. Similarly, the detection device cannot provide specific feedback information of the micro forces for the user or doctor, which is further unfavorable for exercise or rehabilitation training of the user or diagnosis of the doctor.

As shown in fig. 1 to 12, a multi-point micro force sensor 100 of the present preferred embodiment is applied to an in-body type muscle force detecting apparatus 800, wherein the in-body type muscle force detecting apparatus 800 includes a housing 810, a processor 820, and one or more of the multi-point micro force sensors 100, wherein an outer surface of a detection area of the multi-point micro force sensor 100 has an outer layer 830, wherein the processor 820 is installed inside the housing 810, wherein a surface of the housing 810 has an effective operation area, wherein the multi-point micro force sensor 100 is installed on a surface layer of the housing 810 or the effective operation area of the surface, wherein the multi-point micro force sensor 100 is electrically connected to the processor 820, wherein the outer layer 830 is coated on the surface of the housing 810 for improving affinity and flexibility of a human body, which may be a protective layer 830 covering the multi-point micro force sensor 100.

In operation, the integrated muscle force detection device 800 is placed in a human body cavity, for example, a pelvic floor muscle in the pelvic floor cavity, wherein the outer layer 830 can directly contact the inner wall of the human body cavity, wherein the pressure applied by the muscle group action of the human body is applied to the multipoint micro force sensor 100 in the effective working area through the outer layer 830, wherein the multipoint micro force sensor 100 converts the received pressure related information into an electrical signal, and transmits the electrical signal to the processor 820, and then the processor 820 processes the electrical signal in a wired or wireless manner and sends the electrical signal to a user terminal such as a mobile phone, a computer or a cloud terminal, so as to complete the operation. It should be understood that the effective working area refers to a pressed area where the muscular tissue of the body cavity directly or indirectly applies pressure to the surface of the housing 810 when the in-body type muscular strength detection apparatus 800 is operated, wherein the multi-point micro force sensor 100 is precisely arranged in the effective working area to detect and acquire pressure related information such as micro force of muscles or position point force of muscles, pressure change value, frequency, area or size, etc. generated by the muscular tissue. For example, the body-in type muscle force detection device can be completely placed in the human body cavity during operation, so that the surface of the body-in type muscle force detection device can be fully subjected to pressure, that is, the surface of the body-in type muscle force detection device can be the effective working area, or the local pressure-bearing surface of the body-in type muscle force detection device is defined as the effective working area. In this embodiment, the housing 810 of the in-body type muscle force testing device 800 is implemented as an ellipsoidal structure, i.e., the effective working area of the surface of the housing 810 is implemented as an ellipsoidal area. Of course, the housing 810 may also be a square-shaped structure, a triangular-shaped structure, a pipe-shaped structure, or other irregular-shaped structure, and accordingly, the effective working area of the surface of the housing 810 is also implemented as a corresponding shape area, which is not limited herein.

Further, the in-body type muscle strength testing device 800 further comprises an action unit 840, wherein the action unit 840 is operatively mounted to the housing 810, and the processor 820 controls the action unit 840 to perform one or a series of active or passive stimulating, massaging, detecting or exercising actions, etc., wherein the action applied by the action unit 840 can directly act on the inner wall of the human body cavity through the outer layer 830 to stimulate the muscle tissue of the human body cavity to generate one or a series of contraction actions or tension actions. The pressure generated by the contraction of the muscle tissue of the human body cavity can directly act on the outer layer 830 of the in-vivo muscle force detection device 800, and act on the multipoint micro force sensor 100 of the effective working area through the outer layer 830, so that the multipoint micro force sensor 100 can detect and acquire the pressure related information generated by the muscle tissue of the human body cavity, thereby completing the feedback of the results of physiotherapy, rehabilitation or massage of the present operation.

Preferably, the action unit 840 is implemented as a vibration device capable of generating a certain vibration frequency, or can provide different vibration frequencies to actuate the housing 810 to vibrate correspondingly, so that the inner wall of the human body cavity can be directly stimulated by the vibration to generate corresponding contraction action or tension action for feeding back to the multipoint micro force sensor 100. Or the action unit 840 is implemented as a bioelectric stimulation device, which bioelectrically stimulates the muscle tissue of the human body cavity to generate corresponding contraction action or tension action, so that the multipoint micro force sensor 100 detects and acquires corresponding pressure related information.

The outer layer 840 is preferably made of a flexible material such as a medical silicone material, and the outer layer 840 has a certain toughness, and is slightly deformed or buffered when being pressed by the muscular tissue of the body cavity, so as to protect the human body from using the multi-point micro force sensor 100 which is safe and transmits the pressure to the effective working area inside. Or when in use, a user can smear some medical liquid medicine, auxiliary lubricant or other auxiliary articles friendly and safe to human body or medicines for helping to stimulate the muscular tissue of the human body cavity on the surface of the outer layer 840 so as to help complete the operation.

It will be appreciated that the outer layer 840 can seal the housing 810 and the multi-point piezoelectric sensor 100 to prevent the outer layer 840 from preventing liquid from penetrating into the interior of the in-body type muscle force testing device 800 when the in-body type muscle force testing device 800 is cleaned and sterilized or the in-body type muscle force testing device 800 is soaked with a sterilizing liquid, so as to ensure that the internal components are not damaged, etc., or to prevent the multi-point micro force sensor 100 from being able to work normally.

The multi-point micro force sensor 100 of the preferred embodiment as shown in fig. 1 to 4 comprises a set of sub-detection assemblies 10 and an output unit 20, wherein the sub-detection assemblies 10 are mounted on the surface or the surface of the housing 810 of the in-body type muscle force detection device 800, wherein each sub-detection assembly 10 is composed of at least one micro force sensing unit 11, wherein the micro force sensing units 11 of the sub-detection assemblies 10 are electrically connected to the output unit 20 for detecting multi-point pressure related information of the effective working area of the in-body type muscle force detection device 800 and outputting an electrical signal to the processor 820 of the in-body type muscle force detection device 800 by the output unit 20.

Further, each of the sub-test assemblies 10 forms a sub-test area 110, at least one micro-force sensitive test unit 11 is arranged in each sub-test area 110, wherein each micro-force sensitive test unit 11 has a test area 111, i.e. the sub-test area 110 is composed of at least one test area 111, wherein the test area 110 is arranged in the active working area of the housing 810 of the in-body muscle force test device 800, wherein the outer layer 830 preferably covers the test area 110, such that the outer layer 830 provides a buffer protection of the micro-force sensitive test unit 11.

In the present invention, the set of the sub-detecting elements 10 may be implemented as at least two of the sub-detecting elements 10, wherein the sub-detecting elements 10 are electrically connected to the output units 20, respectively. Preferably, each of the sub-detecting elements 10 is electrically connected to the output unit 20 in series with each other, or each of the sub-detecting elements 10 is electrically connected to the output unit 20 in parallel with each other, or a part of the sub-detecting elements 10 is electrically connected to the output unit 20 in series with each other and a part of the sub-detecting elements 10 is electrically connected to each other in parallel with each other, which can be implemented in an algorithm data chain without limitation.

It can be seen that, when any one of the micro force sensing units 11 fails or is damaged or cannot be detected, the sub-detection assembly 10 still has other micro force sensing units 11 to continue to operate, so that the sub-detection area 110 is ensured not to lose data and damage the integrity of the algorithm data chain of the multi-point micro force sensing sensor 100, and the safety and reliability of the detected data are ensured.

Preferably, the output unit 20 is implemented as a piezoelectric conversion circuit, which can convert the received pressure-related information of the micro force-sensitive detection unit 11 into a circuit and send the circuit to the processor 820, and according to different circuit arrangement schemes, the output unit 20 can transmit two, three or more paths of electrical signals to the processor 820, so that the processor 820 can calculate multiple paths of circuit signals by adopting a differential grading algorithm, thereby completing differential comparison of multiple paths of electrical signals and improving detection accuracy.

Of course, the arrangement of the different positions from the sub-detecting assembly 10 and the micro force sensitive detecting unit 11 according to the line arrangement enables the processor 820 to use two-way, four-way, five-way or more types of circuit algorithms, and more accurate detection values are obtained by using differential classification algorithms.

In this embodiment, after the micro force sensing unit 11 collects the micro force of the muscle at a plurality of points of the pelvic floor, that is, the pressure related information, the processor 820 calculates the magnitude of the micro force of the muscle at one or more points in the human body cavity by using an amplifying circuit or an MCU to process and calculate, further determines the pressure related information of the muscle at the points of the pelvic floor, improves the sensitivity of the micro force acquisition of the muscle, so that even the micro force can be converted and amplified into a determined electrical signal, so that the pressure related information can be fed back into the vibration intensity of one or more vibration motors corresponding to the plurality of points, or the intensity of one or more lamps corresponding to the flickering, or the graphic change of one or more images presented on a user side, and so on, so as to enhance the user experience, or visualize the detection result, so that the user or doctor can intuitively and conveniently perform the next exercise or rehabilitation.

Taking the pelvic floor muscle as an example, the in-vivo muscle force detection device 800 is placed in the pelvic floor cavity of the human body to be in direct or indirect force contact with the pelvic floor muscle, wherein one or more of the micro force sensing units 11 of the multi-point micro force sensor 100 can detect the pressure related information of one or more point positions of the pelvic floor muscle, and the pressure related information is fed back and outputted to the processor 820 by the output unit 20, wherein the processor 820 feeds back one or more of the pressure related information to the user side and presents one or more image corresponding graphic changes at the user side.

For example, the light corresponding to some muscle position points with larger stress is brighter, and conversely, the light corresponding to some muscle position points with larger stress is darker. Of course, it may also be a color that displays different lights corresponding to different pressure magnitudes, which is not limited herein.

That is, the sub-detecting elements 10 or the micro force-sensitive detecting units 11 may be arranged in any number or shape at different positions in the effective working area, and it is understood in the art that only the changes or modifications in structure, number and position are included in the scope of the present invention.

For example, the set of sub-detecting elements 10 is configured as four sub-detecting elements, and is numbered in sequence as a first sub-detecting element 101, a second sub-detecting element 102, a third sub-detecting element 103, and a fourth sub-detecting element 104, wherein the first sub-detecting element 101 is composed of one micro-force-sensitive detecting unit 11A, wherein the second sub-detecting element 102 is composed of two micro-force-sensitive detecting units 11B connected in series, wherein the third sub-detecting element 103 is composed of four micro-force-sensitive detecting units 11C connected in series, and wherein the fourth sub-detecting element 104 is composed of four micro-force-sensitive detecting units 11D connected in series. Each of the sub-detection assemblies 101, 102, 103, 104 is arranged laterally in turn on the surface of the housing 810 and is connected in series to the output unit 20, wherein two of the micro-force-sensitive detection units 11B of the second sub-detection assembly 102 are arranged longitudinally on the surface of the housing 810, wherein four of the micro-force-sensitive detection units 11C of the third sub-detection assembly 103 are arranged longitudinally on the surface of the housing 810, and four of the micro-force-sensitive detection units 11D of the fourth sub-detection assembly 104 are arranged longitudinally on the surface of the housing 810. That is, the micro force sensitive sensing units 11A, 11B, 11C and 11D are each laterally arranged in parallel to each other on the surface of the housing 810, wherein each of the micro force sensitive sensing units 11 forms the sensing area 111 of the plurality of points in a vertically and horizontally arranged manner at the effective operation area of the surface of the housing 810 for respectively sensing pressure related information of the corresponding position of the surface of the housing 810.

As shown in fig. 6 to 9, in the present embodiment, the micro force sensitive detection unit 11 includes a detection element 112 and a support member 113, wherein the support member 113 is mounted on a surface or a surface layer of the housing 810 and supports the outer layer 830, wherein the support member 113 forms a buffer cavity 114, wherein the surface of the detection element 112 forms the detection area 111, wherein the detection element 112 is operatively and fixedly mounted on a bottom of the buffer cavity 114, such that the detection area 111 faces the outer layer 830, so that the buffer cavity 113 forms a buffer space capable of buffering a pressure transmitted from the outer layer 830 to the detection element 112, thereby protecting the detection element 112 from damage or sensitivity degradation, and the like, and prolonging a service life. The sensing elements 112 of each micro force sensing unit 11 are connected in series with each other and electrically connected to the output unit 20, so that the output unit 20 can receive pressure-related information of each position point.

In operation, the outer layer 830 deforms towards the buffer chamber 114 under external pressure, wherein the outer layer 830 transmits the pressure to the detecting element 112 at the bottom of the buffer chamber 114 after deformation, so that the outer layer 830 transmits the external pressure to the detecting element 112 after being pressed and buffered by the buffer chamber 114, thereby protecting the detecting element 112 from being directly affected by the larger external pressure to prevent damage.

The detecting element 112 is implemented as a piezoelectric film material, such as AIN, ZNO, PZT or PVDF, which has a low piezoelectric coefficient, and can sensitively convert the pressure received by the surface into pressure-related information such as circuit parameters, and transmit the pressure-related information to the output unit 20, thereby converting the pressure-related information into a current signal, and completing the operation.

Preferably, as shown in fig. 5, the detection element 112 comprises a tray 1121 and a pressure element 1122, wherein the pressure element 1122 is capable of completing the conversion of a pressure signal into an electrical signal, wherein the pressure element 1122 forms the detection area 111 in a middle position of the tray 1121, wherein the pressure elements 1122 of the detection elements 112 of each micro force sensitive detection unit 11 are connected in series with each other for transmitting an electrical signal to the output unit 20.

Of course, the supporting member 113 may also be a cylindrical structure, in which the buffer cavity 114 is formed in a circular hole shape, wherein the bottom of the buffer cavity 114 is disposed on the housing 810, and the detecting element 112 is supported and fixed by the housing 810, wherein the supporting member 113 can be integrally formed on the surface of the housing 810.

It is understood that the side wall of the supporting member 113 may be inclined toward the inside to form the buffer chamber 114 of a circular groove shape with an opening gradually increasing, i.e., the inner side wall of the supporting member 113 is provided in a slope shape or a cambered surface shape or a basin-like bottom shape, wherein the detecting element 112 is disposed at the center bottom of the buffer chamber 114 to provide a good use effect. Of course, the buffer chamber 114 may be configured as an arc-shaped groove, a square-shaped groove, or the like, which is not limited thereto.

In the present embodiment, the coupling hole 1131 is implemented as a hole formed by a groove formed at a sidewall of the support 113 in cooperation with the housing 810, so as to facilitate installation and coupling of the adjacent sensing elements 112. Or the coupling holes 1131 are holes or blind holes such as grooves formed at the middle or upper portion of the side wall of the support 113, it is also possible to couple the adjacent sensing elements 112 to each other.

It will be appreciated that one of the support members 113 of adjacent sub-test assemblies 10 may also be integrally connected together such that each sub-test assembly 10 is integrally secured to the surface of the housing 810 to enhance overall operational stability. Of course, the adjacent supporting members 113 may be adhered, fastened, locked or supportedly fixed to the surface of the housing 810, which is not limited herein.

It should be noted that the supporting members 113 of each micro force sensing unit 11 may be separately fixed to the surface of the housing 810, that is, each supporting member 113 is separately fixed to the housing 810. Or portions of the support members 113 are disposed together, such as the support members 113 of each of the sub-inspection assemblies 10 are secured together, and only two adjacent ones of the support members 113 of adjacent ones of the sub-inspection assemblies 10 are fixedly connected, such that all of the sub-inspection assemblies 10 are fixedly mounted to the surface of the housing 810.

Or the bottom or side of the sensing element 112 may be provided with a heat sink element, such as a heat sink, etc.

As shown in fig. 10, there is further provided a method for manufacturing the multipoint micro force sensor 100 according to the present embodiment, which includes the steps of:

A. forming the sub-detection assembly 10 from at least one of the micro-force-sensitive detection units 11;

B. The sensing element 112 of each micro force sensitive sensing unit 11 is mounted and fixed to the buffer chamber 114 of the support 113 which is fixedly mounted to the housing 810 of the in-body type muscle force sensing device 800, and

C. a set of the sub-detection assemblies 10 is electrically connected to the output unit 20.

It can be appreciated that the sequence of steps A, B and C can be changed arbitrarily, i.e., each step can be performed independently and not sequentially.

As shown in fig. 6 to 9, the multipoint micro force sensor 100 preferably further includes a plurality of protrusions 831, wherein the protrusions 831 are disposed on the inner wall of the outer layer 830, and the protrusions 831 are respectively corresponding to the buffer cavities 114 facing the micro force sensing detection unit 11, so that when the outer layer 830 is pressed and deformed towards the buffer cavities 114 during operation, the protrusions 831 can contact the pressure element 1122 of the detection element 112 in advance and transmit pressure to the pressure element 1122 of the detection element 112, so that the pressure element 1122 of the detection element 112 converts pressure into pressure related information such as circuit parameters, and the outer layer 830 can transmit pressure to the detection element 112 by the protrusions 831 without excessive deformation, thereby improving detection sensitivity, protecting the detection element 112 from being damaged, and prolonging service life.

Further, the shape of the sensing element 112 of each micro force sensing unit 11 is configured as a circular or oval shape or a quasi-circular sheet shape or a square shape or other shape structure, which is arranged just at the bottom of the buffer chamber 114, wherein the protrusion 831 just corresponds to the middle of the buffer chamber 114 and has a spacing tolerance D from the sensing element 112, such that the protrusion 831 can contact the middle of the sensing element 112 to transmit pressure without being hindered by the support 113, or prevent the support 113 from interfering with the protrusion 831 to precisely transmit pressure to the sensing element 112, so that the sensing accuracy of the sensing element 112 is ensured.

In particular, the distance tolerance D of the protrusion 831 from the detection element 112 is implemented to be 0-0.5cm, preferably the distance tolerance D is 0.15cm. That is, the protruding end of the protrusion 831 can contact the detecting element 112, or can be separated from the detecting element 112 by a certain distance, so as to achieve accurate pressure transmission.

Accordingly, the method for manufacturing the multi-point micro force sensor 100 further includes a step D of supporting the protector 830 having the plurality of protrusions 831 on the upper side of the micro force sensing unit 11, wherein the protrusions 831 are respectively and correspondingly oriented to the buffer cavities 114 of the micro force sensing units 11.

Accordingly, the protrusion 831 is configured in a hemispherical structure or a semi-elliptical structure to matingly transmit pressure to the sensing element 112 in the middle of the buffer chamber 114.

Or the micro force sensitive detection units 11 of the same sub-detection assembly 10 are consistent in size, and the micro force sensitive detection units 11 of different sub-detection assemblies 10 are inconsistent in size, so that the sub-sensing areas 110 of the sub-detection assembly 10 at different positions are inconsistent, and the detection areas 111 in the same sub-detection area 110 are consistent in size, so as to adapt to receiving pressures of different sizes or areas at different positions.

In actual operation, the part of the surface of the integrated muscle force detection device 800 has different compression forces or compression areas due to different positions of the muscle tissue of the body cavity or different directions of the applied force. Therefore, according to the different surface stress conditions of the in-vivo muscle force detection device 800, the micro force sensitive detection units 11 with corresponding number and size are arranged in the effective working area, so as to correspondingly set the detection areas 111 with corresponding number and area in the local area of the effective working area, thereby improving the detection accuracy of the multi-point film sensor 100.

For example, if the area of the muscle tissue is larger, the force application area is correspondingly larger, and a larger area of the pressure receiving area on the surface of the in-body type muscle force detecting device 800 can be provided with a larger number of micro force sensing units 11 with smaller size, so that the force applied to the larger area is finely detected by a larger number of micro force sensing units 11, and further, the relevant information of the force applied by the larger muscle tissue can be analyzed from a larger number of data, so that a doctor or a user can more accurately understand the exercise, massage or physiotherapy feedback condition of the larger muscle tissue. Of course, the micro force sensitive detection units 11 of the multi-point micro force sensitive sensor 100 may be implemented in other numbers and sizes to meet the detection needs of the user by arranging the micro force sensitive detection units 11 with different densities in different working areas, which is not limited herein.

Therefore, in operation, the multipoint micro force sensor 100 can still detect and acquire the pressure-related information by the same number and size of the micro force-sensitive detecting units 11 regardless of the pressure applied from the human body cavity to the in-body type muscle force detecting device 800 from any direction.
