Mechanical vibration to electrical energy converter

摘要: Electromechanical devices that generate an electrical signal in response to external source of mechanical vibrations can operate as a sensor and energy harvester for converting vibration energy. The incorporate magnet is movable through gap ferromagnetic circuit, wherein coil wound around portion the circuit. A flexible coupling used attach frame providing alignment it moves or oscillates motion be constrained occur within substantially linear range magnetostatic force develops due magnet. have circuits with multiple arms, array magnets having alternating polarity and, encompass micro-electromechanical (MEM) devices.
