Magneto-thermoelectric generator for energy harvesting

A method of converting mechanical energy to electrical energy comprising:

• (1) providing one or more magneto-thermoelectric generator comprising:
• (a) one or more heat sink;
• (b) one or more magnetic circuit;
• (c) one or more temperature-dependent magnetic materials;
• and
• (d) one or more piezoelectric material, and one or more structure capable of providing a non-linear restorative force, together provided as successive layers adjacent to one another;
• wherein, during use, the magnetic circuit is disposed proximal to or in operable communication with one or more heat source;
• wherein, during use, the heat source and the heat sink are capable of providing a thermal gradient with a hot side and a cold side;
• wherein, the temperature-dependent magnetic material (i) has a thermally induced magnetic transition point within or near temperatures included in the thermal gradient, and (ii) is in operable communication with the structure for providing a non-linear restorative force and the piezoelectric material;
• wherein, during use, the temperature-dependent magnetic material, the structure for providing a non-linear restorative force, and the piezoelectric material are capable of together oscillating between a closed position and an open position;
• and
• wherein, during use, said oscillations are capable of providing mechanical energy to the piezoelectric material, resulting in conversion of the mechanical energy to electrical energy;
• and
• (2) using the generator to convert thermal energy into electrical energy.
