AI Technical Summary
Existing conductive fibers have shortcomings in terms of flexibility, weldability, stretchability and washability, which limit their application in smart clothing and wearable devices. In particular, when collecting and transmitting weak electrical signals from the human body, they have short transmission distances, poor anti-interference capabilities and short service lives.
It adopts a conductive core layer composed of Kevlar fiber and silver plating, with an outer insulating layer and a composite silicone film wrapping layer. It is crocheted into a wavy shape and then attached to the garment by ironing to form a multi-layer composite structure, ensuring conductivity, solderability and washability.
It enables stable and reliable transmission of conductive fibers in smart clothing and wearable devices, possesses excellent conductivity, solderability, and washability, is suitable for collecting and transmitting weak electrical signals from the human body, provides stable and reliable electrical and mechanical connections, resists interference, and meets the needs of long-term use.
