Triboelectric Nanogenerator Introduction A Triboelectric Nanogenerator (TENG) is a device that converts mechanical energy (such as vibration, motion, or touch) into electrical energy by using the triboelectric effect and electrostatic induction . This technology was first developed in 2012 by Professor Zhong Lin Wang and his team at the Georgia Institute of Technology . Since its invention, it has attracted global attention for its potential to power self-sustained electronic devices , wearable technologies , and Internet of Things (IoT) sensors. The motivation behind TENGs is to harvest energy from everyday mechanical movements — for example, walking, typing, or the flow of air or water — to reduce dependency on traditional batteries. 2. Working Principle The TENG operates based on two combined physical effects: (a) Triboelectric Effect When two different materials come into contact and then separate, electrons are transferred from one material to another depending on t...
