Title: Innovative Electromechanical Transduction Mechanisms for Piezoelectric Energy harvesting from Vibration: Toward Micro and Nano Electro-Mechanical Systems
Abstract: Vibration energy harvesting is one the hottest topics addressed by a big part of the scientific community. A lot of transduction mechanisms have been investigated and designed, based mechanical systems and transduction principles in order to recover energy coming from environmental vibrations. In this work, innovative transduction mechanisms will be described, suitable to harvesting energy from weak random vibrations, to rectifying and multiplying voltages avoiding the use of classic solutions based on diodes. Innovative devices will be introduced, based on nonlinear mechanical systems and piezoelectric transducers; analytical models will be provided and simulation results will be shown. Laboratory prototypes and experiments will be also described. Comparisons between simulations and experiments results will be provided in order to demonstrate the goodness of the proposed approaches. Finally, MEMS technologies suitable with piezoelectric energy harvesting, together with a very simple micro scale prototype, will be introduced as encouraging elements for future miniaturization of the devices.
