Definitions
- the invention relates to a planar flexible electrode arrangement for a dielectrically impeded plasma discharge having a central region and an edge region with at least one planar electrode which can be acted upon by a high voltage potential and which is embedded in a planar dielectric forming an upper side and an abutment side, the planar dielectric being at least in the edge portion is in the form of a spirally wound strip and the at least one electrode is formed by at least one electrical conductor extending in the longitudinal direction of the wound strip and terminating in an end face of the strip which is surrounded by the dielectric of the strip, with the exception of only the end face of the strip is electrically insulated in the region of the end surface of the strip with a covering element from the environment.
- Such a planar flexible electrode arrangement is known from EP 2 723 447 B1.
- the formation of the dielectric as a spirally wound strip in the edge region of the electrode arrangement can be used to adapt the effective contact surface of the electrode arrangement on the contact side of the dielectric to a pad in terms of size.
- the spirally wound strip can be shortened at a suitable location by means of a tool in order to reduce the contact surface in the desired manner.
- a dielectrically impeded plasma field can be generated in the required size by means of the electrode arrangement and, for example, act on a skin surface of a human or animal body.
- the skin or another surface to be treated can act as a counter electrode if the surface is sufficiently conductive.
- the electrode is supplied with a high voltage which is sufficient to generate the plasma in an air space between the electrode assembly and the surface to be treated, in particular the skin.
- the dielectric can be formed on its contact surface with a structure in the form of nodules. pen, a grid o. ⁇ . To be provided whose top is formed to rest against the surface to be treated and between the contact points, surfaces o- lines and sufficient air gaps, in which the dielectrically impeded plasma discharge can take place.
- the cut edge is overlapped with an insulating contact element which brings about a contact with the electrical conductor forming the electrode, for example by means of cutting contacts.
- the known electrode arrangement thus allows an adaptation of the effective contact surface of the electrode assembly to a specific application, but does not readily allow a compact and dimensionally stable electrode assembly in the application. For the cutting of the strip a suitable tool must be available.
- the present invention is therefore based on the object to improve a flat flexible electrode assembly of the known type in terms of handling.
- a flat flexible electrode arrangement of the type described is characterized in that over the width of the strip Matenalausappelisme are present and that the material of the dielectric and the at least one conductor is selected so that the strip along with the at least one conductor along the Matenalausappel thereafter is torn off over its width.
- the electrode assembly according to the invention can thus be adjusted in the surface stepwise by tearing one end of the strip of a predetermined length along the material recesses across the width of the strip.
- the material of the conductor must be designed so that the conductor along the Matenalaus traditions is also torn off.
- the material recesses may be through the entire thickness of the dielectric continuous openings. It is essential that the wall of the openings are not interrupted by the material of the conductor, but have a distance from the conductor, so that there is no risk of a rollover of the high voltage to the surface to be treated in the region of the material recesses forming openings. Therefore, sufficient wall material of the dielectric must remain between the opening and the at least one conductor.
- the at least one conductor is formed by a path of a certain width within the dielectric, it may be expedient to reduce the width of the conductor in the region of the material recesses. This makes it possible to realize larger material recesses without affecting the breakdown safety and, moreover, to improve the tear-off capability of the at least one conductor in the region of the material recesses.
- the material recesses do not form continuous openings but merely cause a weakening of the material which ensures a defined tearing along the tear-off line formed by the material recesses.
- a secure insulation of the electrode is to ensure in a simple manner.
- the at least one conductor extends in sections of the width of the strip which are not interrupted by material recesses.
- the tear-off capability of the at least one conductor in the region of the material recesses can be promoted by virtue of the fact that the at least one conductor has perforation openings aligned with the material recesses of the strip in the direction of the width of the strip.
- the defined tearability is secured in particular also for a conductor, which is formed, for example, by a thin metal foil.
- the at least one conductor consists of a plastic provided with conductive additives, which preferably corresponds in type with the material of the dielectric. So for example, it is possible to form both the dielectric and the at least one conductor made of a silicone, wherein the silicone is rendered conductive by the conductive additives for the conductor, so that the required for an electrode electrical conductivity is ensured.
- the conductor can be bonded to the dielectric material-locking, for example in a casting process. In this way, a stable and stable in terms of dielectric strength structure of the electrode assembly can be achieved.
- the spirally wound strip of the electrode arrangement forms strip sections which lie next to each other in the manner of spiral turns. Due to their width and due to their material, these strip sections can be sufficiently dimensionally stable, so that they form a sufficiently stable support surface for the surface to be treated. If necessary. Molded spacer elements can be provided by which the adjacent strip sections in the plane are supported against one another parallel to the surface to be treated. In a preferred embodiment, further material recesses are located along lateral edges of the strip, so that connecting sections exist between adjacent strip sections. In this way, adjacent strip portions are fixed to each other by the connecting portions.
- the corresponding strip end can be detached from the adjacent strip sections by detaching the end to be removed from the adjacent strip cut along the lateral edge by tearing it off.
- material recesses may be formed in the manner described above as material weakenings or as continuous openings.
- the electrode arrangement can have an overall rectangular base area, wherein the strip is formed in one piece from angled rectilinear strip sections.
- the cover member is disposed over the free end of the strip to cover the extending into the end face of the strip at least one conductor insulating.
- the cover element is a contact element for supplying at least one voltage to the at least one conductor.
- the electrode arrangement has two or more conductors, all conductors can be supplied with the same voltage, for example high voltage.
- the plurality of conductors together form an electrode, wherein the surface to be treated acts as a counter electrode when it is sufficiently conductive and is at a sufficiently conductive mass.
- the conductors are each supplied with different polarities of the voltage.
- there is a double voltage difference between the conductors which facilitates plasma formation.
- the surface to be treated can function as a zero or ground electrode, possibly slightly floating.
- the two conductors of the electrode arrangement can serve as electrode and counter electrode, so that a surface plasma is formed on the underside of the electrode arrangement.
- a surface plasma is formed on the underside of the electrode arrangement.
- Such an arrangement is usefully usable only for a superficial treatment of the body provided with the surface to be treated.
- An in-depth treatment, for example, of a wound surface not only located on the skin surface of a body, is markedly improved by the use of the body as a counter electrode.
- the supplied voltage may be an externally generated high voltage, which is needed for the plasma formation.
- the electrode order to provide it with its own high-voltage stage, which generates from a fed (safe or at least less dangerous) the voltage required for the plasma generation high voltage.
- the cover element connects at least two conductors and detects a sensor, for example an impedance sensor, the connection of the conductors for the purpose of switching on the high-voltage stage.
- the conductors connected by the cover member may be conductors that conduct the high voltage when it is ensured that components that are not high voltage resistant are overloaded.
- the two conductors may also be separate conductors which do not conduct the high voltage, but merely serve the impedance measurement and possibly a low-voltage supply.
- the detection of the cover element ensures that no high voltage is generated unless the conductors leading into the end face of the strip are covered by the cover element in an electrically insulating manner.

- the electrode 102 is supplied with a high-voltage potential, wherein the surface of a body to be treated as a counter electrode (floating ground potential).
- the webs 105 serve as spacers to form an air space required for the formation of the plasma, here in the form of the chambers 106, between the surface to be treated and the dielectric 101 with its embedded electrode 102.
- the air space can be ensured in other forms, for example by nubs o. ⁇ . As a spacer, wherein the airspace formed in this case does not have to be completed laterally.
- the dielectric 101 has a central region 107, in which the dielectric is formed in one piece.
- An edge region 108 adjoins the central region 107 radially outward, in which the dielectric is in the form of strips 109 with strip sections 1 10a, 1 10b, 1 10c, 1 1 Od, 1 10e, 1 10f.

- FIG. 20 clarifies that the fifth embodiment in the housing structure 522 has electrical components, which manage without the electrode arrangement without an external electrical energy supply.
- the housing assembly 522 are a battery assembly 523, a control circuit 524 with a microcontroller 525 and a high voltage stage 526 for generating high voltage AC signals to power the electrode 502.
- two of the conductors 502a, 502b, 502c, 502d as two Partial electrodes act, which can be controlled in the same manner as explained with reference to the third and fourth embodiments.

- the controller 524 has the function of allowing the generation of the high voltage in the high voltage stage 526 only when the presence of the cover member 516 has been detected. Otherwise, the conductors 502a, 502b, 502c, 502d opening into the end face of the strip 509 could already lead to a high voltage and be directly touchable. This is prevented by the safety circuit with the cover 516.
