Abstract

There is provided a conductive fiber capable of being sewn, woven or knitted, using conventional methods, into a conductive mesh for use with various wearable electronic devices and/or sensors that make direct contact with the skin. The conductive fiber, when combined with a non-slip fiber, facilitates comfortable electrical communication between different electronic devices and the skin.
