Summary:Harvesting energy from the environment has been widely investigated to power and maintain low-power devices. This paper reviews the potential energy sources, piezoelectric conversion mechanism, recently proposed piezoelectric energy harvesters (PEH), and micropower management circuits. It can be concluded that the output power of PEH is still comparatively small, especially when the ambient excitation frequencies deviate from PEH’s resonant frequency. Future work should focus on tuning or widening the operate frequency of PEH so that it can match the ambient vibration frequency at all time. Moreover, flow energy harvesting techniques compatible with MEMS techniques demand in-depth study to facilitate the fabrication of micro PEHs.
