Abstract
Existing IoT sensor nodes operate by receiving energy from a battery. But due to the characteristics of sensor nodes that are widely distributed for collecting various information, there is a disadvantage that the battery needs to be periodically replaced. In order to overcome this disadvantage, energy can be harvested from sunlight or high-temperature steam through an energy harvesting system. However, since the harvested power is quite limited, it is difficult to use applications that require instantaneous high power such as communication. We propose the design of the high-power energy harvesting system where a switch control unit compensates for the limited harvested energy with the energy storage device such as a capacitor. To verify the proposed system, an energy harvesting system based on sunlight was implemented, and we confirmed the maximum supply power to the application and the maximum supply time according to capacity of the energy storage device.
