Abstract: Wireless Sensor Network (WSN) node can be described as infrastructure with fewer sensors that are connected wirelessly, forming a network that is used to gather important data/information from a difficult reach environment. These WSN nodes transmit the required data according to the injected queries wirelessly. These WSN nodes are generally applied in many applications, including military surveillance, agriculture, buildings, universities, dams, under the sea, high altitudes, etc. Since some of these areas are difficult to approach and reach, it is difficult to replace or recharge their battery manually, due to which their lifetime suffers, which ultimately causes interruption and unnecessary delay in the research work. So to overcome this issue, the idea of self-powered WSN nodes came into play. The self-powered WSN nodes recharge itself using the natural sources of energy that are openly available in the environment, and the two most commonly available sources of energy are solar and thermal energy. In this paper, some of the energy harvesting models/systems are discussed, which uses thermal and solar energy as the main source of energy in powering the WSN nodes. In this paper, some important conclusions are made by comparing different energy harvesting model.
