Energy harvesting technology renders a solution of powering small electronics by harnessing energy from ambient energy sources, such as solar, radio frequency (RF), thermal, and vibration. The rapid development of micro-electronic and micro-electromechanical systems (MEMS) has dramatically reduced the power supply demand. For example, the power consumption of some up-to-date embedded micro-controllers in ultra-low-power mode has been reduced to about 30–250 nW. Therefore, employing energy harvesting technology to provide a sustainable power supply has become possible in a wide range of applications, including wireless remote sensors for structural health monitoring [9], implanted sensors for medical devices, etc.
