The first waterproof fabric-based multifunctional triboelectric nanogenerator that can produce electricity from natural tiny impacts (rainswinds)body movements is presented. It can not only serve as a flexible, adaptive, wearable,universal energy collector but also act as a self-powered fabric-based interface. This multifunctional yet nimble energy device can provide new vision for decentralized, remote,wearable energy technologies.

The first multifunctional elastic (650) fiber that can scavenge biomechanical energyelectromagnetic energy from surrounding electrical appliances is developed as a wearable power providervarious self-powered sensors. These findings optimally unify mechanical freedomthe capability of harvesting biomechanical energyelectromagnetic energy from surrounding electrical appliances as well as self-powered sensing in a single fiber.
