Conductive Organic Threads as Electrical Interconnects for Smart Clothing and Non-metallic Electrodes for Clinical Applications

BACKGROUND Organic conductive fibers are a combination of electric wires and textiles having characteristics of both used to transfer electric current. Conductive fibers consist of a non-conductive or less conductive substrate, which is then either coated or embedded with electrically conductive elements. Because it is thin and flexible, can take many...
