Actuating and Sensing Using Piezoelectric Cantilever

Micro-power generation systems have gained considerable research attention due to the rapid development of micro-electromechanical systems and wireless technologies. To this day batteries serve as the most common power source for remote wireless systems. However, these power systems have grown impractical for large networks and small devices, where replacing depleted batteries becomes difficult. Therefore, alternative solutions characterized by a renewable power supply of reasonable power density have been suggested. Ambient vibrations offer a plausible source of energy for conversion into usable electrical power. Present work aims at modeling and analysis of piezoelectric-based vibration-harvesting devices using Ansys and matlab software. Static analysis of piezoelectric cantilever is carried out in Ansys.
