Spiral Steel Wire Based Fiber-Shaped Stretchable and Tailorable Triboelectric Nanogenerator for Wearable Power Source and Active Gesture Sensor

Owing to the great robustness, continuous conductivity, and geometric construction of a steel wire electrode, the FST–TENGs demonstrate high stability, stretchability, and even tailorability. By knitting several FST–TENGs to be a fabric or a bracelet worn on the human body, it enables to harvest human motion energy. The FST–TENGs can also be woven on dorsum of glove to monitor the movements of gesture.
