A wearable, fibroid, self-powered active kinematic sensor based on stretchable sheath-core structural triboelectric fibers

A kinematic sensing fiber that is highly stretchable and self-powered is developed based on a triboelectric sheath-core structure. In which a unique built-in wavy is built in the core fiber and provides controllable electric contact to the intrinsically stretchable sheath fiber tube. The new design offers opportunities for stretchable and active sensing fibers with full potential in human motion monitoring.152
