| Abstract |
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. In this dissertation,designed by the pipeline flow driven a piezoelectric energy harvester is proposed and fabricated to convert environmental vibrations into electricity.
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 effect will be slight on generate electricity.
By exerting impact force, the electric power is proportional to the frequency of the external force relations.Under the action of the diameter ratio of 0.2646 and flow 35 L/min, the piezoelectric elements in the parallel maximum output of the fully loaded is 142.13μW.
In summary, this preliminary study shows that it is a feasible scheme for the application of piezoelectric materials in harvesting electricity from environmental
vibrations. The results and conclusions of this work are still invaluable for guiding the development of high efficient piezoelectric harvesters in the future. |
