Patent ID: 7034440

Claim:
A micro-electro-mechanical generator, comprising: 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, the upper diaphragm and the lower diaphragm 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, the upper diaphragm and the lower diaphragm adapted to generate electric energy whenever being deformed; and a fluid chamber charged with working fluid, the fluid chamber having an upper end defined by the upper diaphragm, a lower end defined by the lower diaphragm and a lateral wall formed between the upper end and the lower end and having a configuration causing that a volume of the fluid chamber in the second position is larger than that of the fluid chamber in the first position.
