Development of high-current density triboelectric nanogenerators
based on stacked grating structures
Professor Jongbaeg Kim’s research team from the Department of Mechanical Engineering (co-first authors of this study are Hee-jin Ko and Heejun Seong) has developed a triboelectric nanogenerator (TENG) featuring a stackable grating structure. By converting vertical displacement into lateral sliding motion, the newly developed TENG achieves a high output current density while minimizing the increase in stack height. Moreover, thanks to its robust design, the device maintained stable performance even after 45,000 consecutive cycles. Remarkably, with fewer than six mechanical deformations, it successfully powered and transmitted data from a wireless environmental sensor, demonstrating strong potential for applications in small-scale vertical vibration-based energy harvesting. These research findings were published in Nano Energy (Impact Factor: 16.8) in December 2024
