Hybrid generator using thermoelectric generation and piezoelectric generation

A hybrid generator comprising:

• a thermoelectric generator;
• and
• a piezoelectric generator disposed on the thermoelectric generator,
• wherein the thermoelectric generator comprises a first insulating layer, a second insulating layer disposed on the first insulating layer, and a thermoelectric structure disposed between the first and second insulating layers,
• wherein the piezoelectric generator comprises a first electrode disposed on the second insulating layer, a second electrode disposed on the first electrode, a piezoelectric structure disposed between the first and second electrodes and including a plurality of piezoelectric nanowires, a third insulating layer disposed on the second electrode to be in direct contact with the plurality of piezoelectric nanowires and between the piezoelectric structure and the second electrode, a fourth insulating layer disposed on the first electrode, and a seed layer disposed between the plurality of piezoelectric nanowires and the fourth insulating layer to grow the plurality of piezoelectric nanowires, and
• wherein the third insulating layer extends continuously between each of the plurality of piezoelectric nanowires.
