The invention relates to a thermoelectrical microgenerator used in the field of medical monitoring of physiological parameters, in supplying wireless systems and microelectrical and mechanical systems where powers of 1...10 μW are necessary. According to the invention, the microgenerator comprises a support plate () made of glass textolite in which there are mounted two thermocouples consisting of some plates () where two plates () are made of CaLaMnO, being disc-shaped n-type semiconductors, and the other two plates () are made of CaCoO, being also disc-shaped p-type semiconductors and a set of electrical connectors () of Ag deposited by stencil printing, a connector () for connecting in series the thermocouples and some connectors () for picking up the electrical voltage.
