ABSTRACT:
The conversion of heat energy to electrical energy is realized by coupling memory materials to piezoelectric materials or to composite magnetoelectric materials and by subsequent hot-cold-strain cycling of the memory material. Embodiments of the invention provide solid state inverters, particle acceleration and focusing devices, and automatic hot-cold-strain cycling motor, and high voltage heat to electricity converters.
