• . Based on the coupling of triboelectrification and electrostatic induction, the switch can be used as a triboelectric generator (TEG) [90]. The TEG usually contains an insulated diaphragm and the switch is normally closed. The combination of triboelectrification and the elastic restoring force causes the

Due to contact electrification (CE, or triboelectrification) [86], opposite charges will be induced when the two materials are separated by a mechanical force, which will correspondingly generate a potential difference between the two materials due to
