A system for converting thermal energy into electrical power includes a temperature-sensitive element held in a frame by its two ends between a heat source and a cold source producing a thermal gradient. A piezoelectric element is positioned between the frame and at least one end of the temperature-sensitive element. The temperature-sensitive element is configured to deform cyclically between two states under the action of the thermal gradient. With each cyclic deformation, a stress is applied to the piezoelectric element via the one end.

System for converting thermal energy into electrical power

A device for converting thermal power into electric power includes many conversion cells arranged inside and on top of a substrate. Each conversion cell includes a curved bimetal strip and first and second diodes coupled to the bimetal strip. The diodes are arranged in a semiconductor region of the substrate.
