A Study on the Resonance Frequency of the Cross-Shaped Piezoelectric Generator According to Change in Elastic Body Thickness and Tip Mass

摘要: Over the past few years, research about generating system with piezoelectric ceramics has been conducted. To compensate problem of low power than other harvesters, many researchers have studied generator for obtaining high output. And until now various types developed. Cross-shaped using only one vibration source four elastic body legs which same mode. So they resonance frequency under vibration. Elastic thickness and tip mass in design parameters influence on frequency. The relation to output characteristics. In this paper, characteristics depending were studied. material used here was SUS304 As a result, decreased decreasing thickness. is expected be as an energy harvest from at so...
