Abstract: Efficient pyroelectric energy conversion would enable portable, wireless power generation capabilities for the Army. This technology relies on the pyroelectric effect in ceramic materials, where the dielectric polarization has a strong temperature dependence. In order to evaluate pyroelectric systems, one must precisely measure and control electric field and temperature while evaluating alternating pyroelectric currents. This technical report describes the modeling, assembly, and performance of a custom pyroelectric energy conversion testing system. This system is used to evaluate a lead zirconate titanate thin film pyroelectric capacitor as an energy conversion system. The conversion cycle and future outlook are presented.
