Development of temperature change power generator for IoT devices using pyroelectric materials

Abstract

This paper describes feasibility of a pyroelectric power generator (PEG) for powering sensors in IoT devices. This generator utilizes the pyroelectric effect, which is a change in polarization with temperature variation. The PEG devices have a simple structure and can generate electricity from exhaust heat, such as from an engine and a compressor. In this study, a simple power generation analysis and a proof-of-concept experiment were conducted to clarify the relationship between temperature change and amount of generated power of PEG. As a result, it became clear that the PEG can be used as a power source of the IoT devices.
