Summary

Meaning of Energy Harvesting

Low-power wireless remote monitoring sensors have been widely used with the development of chip technology and highly integrated circuit technology in recent years. These small sensors play an important role in the Internet of Things. Micro-energy harvesting is a collection of available energy in the environment, such as wind energy, solar energy, thermal energy, tidal energy, mechanical vibration energy, and even energy in living organisms These clean energy sources are used to power a variety of low-power, miniaturized sensor nodes. Self-powering of small electronic devices can be achieved by obtaining micro-energy from the environment. These micro-systems usually operate at intervals, so power consumption requirements can be further met with the help of energy storage and management systems such as supercapacitors to power the sensor nodes
