Abstract
An energy harvesting device, system and method are described. The energy harvester collects acoustic energy and transforms it into electrical energy for use by a sensor. The energy harvester utilizes a piezoelectric device, which may be encased, either wholly or partially, within an acoustic chamber. Alternatively, the piezoelectric device may be entirely exterior to the acoustic chamber, which acts to amplify the collected acoustic energy.
