Engineering design based high output energy harvester
1. Ion-Enhanced Field Emission energy harvester
Conventional TENGs have some limitations including air breakdown, field emission and imbalance between high voltage and low current. Our group can design high output electrical discharge TENG via concentrated on the metal-metal contact local point design and new electrical mechanism that overcome basic TENG limitations.
2. Capacitor-Integrated energy harvester
Our group first demonstrates a new TENG mechanism involving the Leyden jar effect, where a capacitor is combined with the TENG. The Capacitor-integrated TENG is composed of a long sheet metal utilized generating high output. The new mechanism is expected to be a potential solution for high-power TENGs and to allow TENGs and to allow to be used in portable applications
3. AC/DC Convertible Pillar-Type TENG
TENGs inherently produce an AC output as two materials repeatedly contact and separate. The generation of repeated voltages necessitates additional electrical component such as a diode or rectifier to the TENG device. Our groups can design AC/DC convertible with mechanical movement of moving electrode. Moreover, we can fabricate a miniaturized and portable design of the TENG to harvest mechanical energy in daily life activities
