Harvesting electrical energy from thermal sources using pyroelectric conversion techniques has been under investigation for over 50 years, but it not received the attention that thermoelectric harvesting have during this time period. This lack of interest stems early studies which found efficiencies achievable materials were several times less than those potentially with thermoelectrics. More recent modeling and experimental shown can be cost competitive thermoelectrics and, new temperature...
