Application Requirements

Enabling technologies for wireless sensor networks have gained considerable attention in research communities over the past few years. With the advantage of high power density, piezoelectric vibration energy harvester is promising in self-powered wireless sensor networks. In this work, modeling of piezoelectric generator based on a bimorph cantilever is discussed and functional characteristics of the bimorph piezoelectric cantilever are given. Corresponding step-up energy harvesting circuit according to the practical application requirements is developed. Then an integrated environmental vibration energy harvester with a size of approximately 83mm × 55mm × 12mm was fabricated. The results shows that the energy harvester is able to provide a stable 3.3V supply voltage under 37Hz working frequency.
