Introduction
the development of a permanent power source for self-sustainable wireless sensor networks is essential in order to reduce the maintenance costs and increase the operational time of sensor nodes. Accordingly,over the past decade researchers have actively studied various energy harvesters that generate power form sources such as ambient light, heat, motion, electromagnetic waves and other unused sources of energy. One energy harvester driven by ambient vibrations has attracted special attention because it can easily gain energy form sources of movement such as human physical motion. This project states a liquid-based electrostatic energy harvester that converts the mechanical energy of human-motion-induced vibrations to electrical energy.
background
Comparing to conventional energy source, energy harvester provides sustainable and clean energy source. Comparing to piezoelectric energy harvester and electromagnetic energy harvester, electrostatic energy harvester has high output voltages; their components are built in low-cost parts, is easy to adjust the coupling coefficient and reaches high coupling coefficients, and increases capacitances through the reduction of size. These advantages are significant in small-scale energy harvester and in low frequency range operation.
