Electret Generators: The Unsung Heroes of Motion Energy Harvesting
Electrical Engineers
System Engineers/ArchitectsElectret generators are the unsung heroes of energy harvesting. These electrostatic generators convert ambient mechanical energy – such as vibration, motion, and pressure – into electrical power using electret materials. With no coils, no magnets, and few moving parts, they use electrostatic induction to convert subtle movements into usable current, with no external priming or charging required. Their simplicity and durability make them effective...
