Energy harvesting from environmental vibration nowadays is feasible because of natural oscillations like that caused by air or liquid flow and by exhalation or the heartbeat of a human body. This vibration frequency is typically low (in order of less than 1 kHz). Accordingly, low-frequency vibration based energy harvesting systems are an important research topic; these systems can be used for wearable or implantable devices.

Piezoelectric vibration based harvesters are not expensive and do not require external voltage sources, making them a viable alternative to implement the energy harvesting system.
