Tunable vibration energy harvester and energy harvesting method

机译:可调振动能量采集器和能量采集方法

摘要

An energy harvester (12) is provided which includes an energy conversion device (24) configured to convert vibrational energy to electrical energy, a mass (30) coupled to the energy conversion device, and at least one selectively adjustable biasing mechanism (32) coupled to the mass. Selectively adjusting the biasing mechanism (32) adjusts a resonance frequency of the energy conversion device (24) and the mass (30). Preferably, a piezoelectric cantilever (29) is used and the compression distance of a spring (60) is adjusted by an actuator (46).
