Integrated dual-sided all-in-one energy system including plural vertically stacked dual-sided all-in-one energy apparatuses

A dual-surface energy system comprising a plurality of dual-surface energy apparatuses, each of the plurality of dual-surface energy apparatuses comprises:

• an energy-harvesting device comprising a first electrode pattern disposed on a first surface of a substrate and generates electrical energy by harvesting energy based on a temperature difference between a first side and a second side of the first surface;
• and
• an energy-storage device comprising a second electrode pattern disposed on a second surface of the substrate opposite to the first surface and stores the electrical energy harvested by the energy-harvesting device,
• wherein the second electrode pattern comprises a capacitor electrode and a current collector connected to each other, and the current collector extends to a first end of the substrate and a second end of the substrate disposed opposite to the first end,
• wherein the current collector is disposed at an entire surface of at least one of the first end and the second end,
• wherein the first electrode pattern is disposed at an edge surface of the at least one of the first end and the second end,
• wherein the energy-harvesting device and the energy-storage device are electrically disconnected when a flat alligator clip is disposed at a center of the at least one of the first end and the second end,
• wherein the energy-harvesting device and the energy-storage device are electrically connected when the flat alligator clip is disposed at the edge of the at least one of the first end and the second end, and
• wherein the plurality of dual-surface energy apparatuses are vertically stacked and are interconnected in series.
