Piezoelectric energy harvesting device based on quartz as a power generator

Abstract

The idea of harvesting ambient vibration energy to generate electricity has become a promising research field over the past decade due to the reduced power requirements of small electronic components. The motivation of vibration-based energy harvesting (EH) is to power such devices (e.g., sensor networks used in monitoring applications) by using the vibration energy available in their environment such as electromagnetic, electrostatic, piezoelectric, and magnetostrictive transduction mechanisms. Due to its large power densities, ease of application, and feasibility of fabrication in microscale, piezoelectric EH has received the attention.
