Triboelectric Electromagnetic Separation

Triboelectric effect - Wikipedia

A Triboelectric Series is a list of materials, ordered by certain relevant properties, such as how quickly a material develops a charge relative to other materials on the list. Johan Carl Wilckepublished the first one in a 1757 paper on static charges. Materials are often listed in order of the polarity of charge separation when they are touched with another object. A material towards the bottom of the series, when touched to a material near the top of the series, will acquire a more negative charge. The farther away two material…

A Water‐Proof Triboelectric–Electromagnetic Hybrid ...

A waterproof triboelectric–electromagnetic hybrid generator (WPHG) for harvesting mechanical energy in harsh environments is reported. Since the mechanical transmission from the external mechanical source to the TENG is through a noncontact force between the paired magnets, a fully isolated packaging of TENG part can be easily achieved.
