Abstract

A novel thermoelectric energy generator, which is based on pyroelectric power generation caused by periodic temperature change of a ferroelectric material, is developed. A bulk lead-zirconate-titanate (PZT) ceramic is attached on a bimetal disk. This bimetal disk is placed between heat and cold sources, which causes reciprocatory motion between the heat and cold sources. The temperature of the PZT ceramic is periodically changed due to contact heat transfer, which produces pyroelectric current. Maximum output power of 1.1 nW is obtained with the reciprocation frequency of 1.7 Hz when temperature difference is 247°C.
