piezoelectric power generator
||Mechanical energy exists all over the place in our living, and vibration is the most common way of mechanical performance. Micro-electromechanical systems, the application which integrate techniques and combine different field of research, make it possible to convert vibration into electrical energy by using piezoelectric materials; moreover, it become a small piezoelectric power generator.|
The thesis set up an equivalent circuit model based on the principle of piezoelectric and cantilever mechanics for experimenting the model’s exactness; consequently, model shows that resonant frequency has no effect on generate electricity when amplitude was fixed.
The thesis attempts to change the shape of unimorph for enhancing its power generation. By using different sharp of unimorph, the experiment demonstrate that power generation have direct ratio with frequency at amplitude of 5mm. Moreover, different shapes of the unimorph at frequency of 16Hz have different power output; the disparity among power output might up to 1.78 times.
