Definitions

  • Electronic textiles are an emerging and developing field of technology that can monitor physiological conditions, provide medical services, or serve as a human-machine interface (HMI).
  • HMI human-machine interface
  • Smart fabrics and clothing with similar functions need to be easy to use, beautiful in appearance, and easy to wash.
  • Connectors need to be easy to connect and remove for easy washing.
  • the connections between textiles and electronic products are: snapbuttons are by far the most commonly used connectors in electronic textiles.
  • the main application of Pogopin in electronic textiles is to connect rigid circuit modules to flexible circuits in clothing. In this regard, they are usually small in size with a diameter of 1-2 mm, allowing many connection components to be installed in a smaller area, which is relatively comparable to alternatives such as snaps.
  • Wireless communication is an established method for transmitting power or data in electronic devices, such as wireless smartphone charging or near-field communication (NFC) between electronic devices using inductive coupling.
  • Inductive coupling has been proposed as a method to achieve 3D integration in integrated circuit technology, or as a connector for smart glasses, where power and data must be transmitted through hinges.
  • Level 1 (detachable): The electronic device is attached to the fabric in a way that the electronic device and the fabric can be separated without damaging the electronic device or the fabric, such as in a pocket or pouch.
  • Level 2 (attached): The electronic device is attached in a way that it cannot be removed without destroying or damaging the electronic device or the fabric, such as gluing, soldering or sewing the electronic device to the fabric.
  • Level 3 hybrid solution: One or more components are made of textile or using textile finishing, and are combined with additional electronic components (such as e-textile woven tape with additional LEDs or sensors).
  • Level 4 All electronic components are made of textile or using textile finishing processes.
  • Removable interconnect technologies for woven electronics and e-textiles include textile closure methods such as snaps, pogo pins, conductive hook and loop (Velcro), zippers, connector pins, and wireless connections through inductive coupling or NFC. But there are still many problems with the above.
  • Pogo pins for rigid electronic applications, such as connecting a camera body to a lens, or for charging, as seen in many Apple laptop chargers.
  • Pogo pins which consist of spring-loaded pins, are designed to mate with flat contact pads. This flat contact pad is not made of fabric, but a metal cylinder made on a circuit board (PCB). External pressure is required to make the pins and flat contact pads contact each other to form an electrical connection.
  • Magnets are usually used for this purpose, or the pogo pins can be mounted in a crimped plastic housing, which has the problem that the magnets are prone to peeling off, and there are also protruding plastic or rubber materials on the fabric. This is shown in the Sensoria smart socks on the market.
  • the insulation is encapsulated with hot melt film or fabric instead of plastic, PCB circuit board or rubber.
  • the magnetic connection can be replaced by buttons, snapfasteners or Velcro.
  • Another connector for smart clothing benefits from 2 to 12 or more connector pins.
  • This connector system includes plug contacts permanently connected to one side of the fabric and top and bottom insulators, and socket contacts mounted on the surface of the electronic circuit board. These connectors use snap-on contacts, so the connector has grooves protruding from the fabric, but the electronics are made on the fabric. Because it is a variation of traditional electrical connectors, it is not handled in the way of fabric electronics hot melt film or fabric. From the description of the above literature, it can be seen that the connection application between clothing and electronic devices still has defects and is not convenient enough, and needs to be further improved. However, to date, a suitable design has not been developed, and common products and methods do not provide suitable solutions and structures for the above problems. Therefore, how to create a new method and article for connecting cloth with electronic devices?
