Patent ID: 7800278

Claim:
An energy harvesting device, comprising: a ferromagnetic component suitable to be arranged between a heat source and a heat sink; a mechanical assembly structured to support said ferromagnetic component in a first configuration such that said ferromagnetic component is in thermal contact with said heat source and in a second configuration such that said ferromagnetic component is in thermal contact with said heat sink, said mechanical assembly structured to have a transient state of motion due to said ferromagnetic component satisfying first and second conditions, namely a first condition when a temperature of a ferromagnetic material of said ferromagnetic component T is less than Tc, and a second condition when the temperature of the ferromagnetic material of said ferromagnetic component T is more than Tc, wherein said mechanical assembly comprises an electromechanical transducer constructed and arranged to produce electrical power while said mechanical assembly is in said transient state of motion between said first and second configurations, and wherein said mechanical assembly comprises a shape-memory component.
