Description

Energy storage apparatus based on harvesting The present invention relates to a harvesting-based energy storage device, and more specifically, to an energy storage device for collecting energy from an surrounding environment, such as electromagnetic waves present in the air, converting it into electrical power, and storing it. Generally, energy storage devices are widely used as a key component enabling stable power supply in various electronic devices, home appliances, and industrial facilities. Conventional energy storage devices have primarily utilized chemical batteries such as lithium-ion batteries or energy storage devices such as supercapacitors, and these devices are typically structured to be charged via a power grid or an external power source. However, since this method relies on external power infrastructure required for charging, its use is limited in environments where portability is required or the power grid is unreliable. To address these limitations, so-called energy harvesting technology, which collects energy such as light, heat, vibration, and electromagnetic waves present in the surrounding environment and converts it into electricity, has been researched. Representative examples include light energy conversion using solar panels, vibration energy harvesting using piezoelectric elements, and wireless power harvesting that collects electromagnetic waves with antennas and converts them into electricity. These technologies have the advantage of reducing dependence on external power sources and enabling autonomous power supply in various environments. However, existing energy harvesting-based storage devices have problems such as low conversion efficiency or limited application range due to reliance on specific energy sources. For example, solar-based devices are difficult to utilize in lightless indoor environments, and vibration-based devices require specific mechanical conditions to ensure stable output. In the case of electromagnetic wave-based devices, there were limitations such as a restricted harvestable frequency band and energy loss during the efficient conversion and storage of harvested energy. Therefore, there is an increasing need for new types of energy storage devices capable of more efficiently collecting various forms of electromagnetic energy generated in the surrounding environment and stably converting and storing them.
