Abstract
Thermoelectric device can convert waste heat to electric power. Perovskites that have stability and safety in air are investigated for thermoelectric materials. We prepared these (p,n type) and insulator materials, and applied them to the process of chip monolithic ceramic capacitor. This thermoelectric device contains 25 pairs and generated 26 mW (40mW/cm2) of electricity when this were heated to 673K on one side and cooled to 313K on the other.
