“…In 2012, Prof. Zhong Lin Wang and his team successfully developed the first TENG device capable of converting mechanical energy into electricity . Since then, TENGs have found numerous potential applications that require long-term sustainability, including smart homes, wireless sensor networks, security systems, health monitoring, , gas sensing, , motion detection, powering electronic devices, , and robotics . The TENG operates in four different modes, namely, contact-separation mode, single-electrode mode, relative sliding mode, and free-standing mode, which allow their adaptation to diverse applications utilizing various types of mechanical motions. , …”
