Ferroelectric material losses in devices ranging from sonar transducers to energy harvesters result in the conversion of energy to heat. Under small amplitude sinusoidal drive, either electrical or mechanical, the losses are expressed in terms of a l

In 2014, almost 60% of thermal energy produced in the United States was lost to the environment as waste heat. Ferroelectric based pyroelectric devices can be used to convert some of this waste heat into usable electrical energy using the Olsen cycle

Power can be generated by rapidly driving a poled ferroelectric material through a ferroelectric to antiferroelectric phase transformation. The power generated depends on the maximum remnant polarization that can be obtained in the ferroelectric stat
