A Self‐Charging Power Unit by Integration of a Textile Triboelectric Nanogenerator and a Flexible Lithium‐Ion Battery for Wearable Electronics

A novel integrated power unit realizes both energy harvesting and energy storage by a textile triboelectric nanogenerator (TENG)-cloth and a flexible lithium-ion battery (LIB) belt, respectively. The mechanical energy of daily human motion is converted into electricity by the TENG-cloth, sustaining the energy of the LIB belt to power wearable smart electronics.
