Abstract: There is provided a micro power generator enhanced in efficiency and power generation output, and having an increased temperature range for operation. The micro power generator comprises: a high-temperature heat source; a low-temperature heat source; an enclosed body containing a working substance therein, the enclosed body being deformable by means of a phase change of the working substance between a first shape wherein heat can be transferred from the high-temperature heat source and a second shape wherein heat can be transferred to the low-temperature heat source; a permanent magnet constituting the enclosed body, the permanent magnet being maintained in a first position when the enclosed body has the first shape and in a second position when the enclosed body has the second shape; and a wire in which an electric current is induced by a movement of the permanent magnet.

Abstract: A micro-electro-mechanical generator is provided with a housing having a heat source and a heat sink opposite to the heat source in the housing. An upper diaphragm and a lower diaphragm separated from the upper diaphragm by a constant distance are further provided, which are deformable between a first position where the lower diaphragm is thermally connected to the heat source while the upper diaphragm being thermally shut off from the heat sink, and a second position where the upper diaphragm is thermally connected to the heat sink while the lower diaphragm being thermally shut off from the heat source. Further, the upper diaphragm and the lower diaphragm are adapted to generate electric energy whenever being deformed.
