The
nanogenerator could become an integrated part
of an electronic device — for example, as its back panel or housing — and automatically harvest energy from ambient vibrations to power the device directly.
Triboelectric
nanogenerators (TENGs) are small devices that convert movement into electricity, and might just be what bring us into an era
of energy - harvesting clothes and implants.
Ting Liu at the Chinese Academy
of Sciences in Beijing and her colleagues built the
nanogenerator by sandwiching a layer
