THERMOELECTRIC GENERATOR COMPRISING A DEFORMABLE BY-LAYER MEMBRANE EXHIBITING MAGNETIC PROPERTIES

摘要

An electrical generator is composed of a bi-layer membrane enabling the conversion of a thermal energy into electrical energy. The bi-layer membrane is deformable and includes at least two layers having different thermal expansion coefficients. The membrane moves between positions in a reversible fashion in response to heat dissipation and as a function of two flexing temperatures. A magnetic structure associated with the membrane functions to set the flexing temperatures as a function of ambient temperature.

1. An electrical generator, comprising:
a bi-layer membrane configured to enable conversion of a thermal energy into an electrical energy, said bi-layer membrane comprising a deformable membrane comprising at least two layers whose thermal expansion coefficients are different, wherein the membrane is deformable in a reversible fashion between a first position situated near to a hot source and a second position situated near to a cold source when temperature of the membrane reaches a first flexing temperature and a second flexing temperature, respectively; a conversion circuit configured to convert the deformation of the membrane into electrical energy; a first magnetic structure rigidly fixed to the deformable membrane; a second magnetic structure interacting magnetically with the first magnetic structure so as to increase a value of the first and second flexing temperatures of the membrane in response to increase in temperature of the hot source.
