Tribotronic sensor enables self-powered human-machine interaction

Researchers have developed an ultra-miniaturized, highly sensitive tribotronic sensor capable of generating its own energy for human-machine interaction. This advancement in tribotronics utilizes contact electrification—the same phenomenon responsible for static electricity—to create self-powered sensors that meet the growing demands for miniaturization and low energy consumption in intelligent devices.

The device features a rapid response time of 127 milliseconds and maintained stable performance through 1,000 operation cycles without perceptible degradation. According to Professor Jaekyun Kim of Hanyang University, this technology could significantly improve electronic skin systems, allowing robots, prosthetic devices, and wearable electronics to perceive touch, pressure, and proximity with greater precision, leading to safer and more reliable human-machine interfaces.
