Abstract

The development of micro power supply technologies for mobile phones and portable electronics has increased in recent years. Methods of self power generation using the vibration loads of structures have attracted attention as the power supply technologies. The purpose of the study is to develop a high- efficiency PZT generator element that utilizes the vibration loads in the support members of a structure. However, piezoelectric elements only generate power in the order of several microwatts, so improving their power generation capacity is of the utmost importance. The purpose of this research is to develop a power generation element with higher power generation characteristics and to develop an autonomous state monitoring system using this element as a power source. In this paper, we report the results of a verification test of an autonomous condition monitoring system that employs a general-purpose small air compressor as a vibration source and drives an acceleration sensor by vibration power generation using a La-doped stacked PZT element.
