펜 적용을 위한 압전 효과의 다중 발전 방식 연구

Abstract

Piezoelectric technology is used as an energy harvester that converts mechanical energy into electrical energy, or as an actuator that converts electrical energy into mechanical energy. This technology attracts the interest of many researchers all over the world and is applied to various fields. However, piezoelectric power generation as a harvester has a low current and its application is limited. Piezoelectric energy harvesters that convert mechanical energy into electrical energy use abandoned vibrations or impacts that occur in everyday life. For example, mechanical energy generated by vibrations in bridges, wind, and waves is suitable for use with a piezoelectric energy harvester. In this study, two methods of generating polarization, and structures that have both methods simultaneously in a single motion were investigated. And the investigated findings were applicated to a pencil. Two types of piezoelectric harvester were designed, and the two types of power were simultaneously generated by the movement of the pencil and were stored. The stored energy can be used as auxiliary power for a load such as wireless communication for transferring data.
