About
Yoonsang Ra is a leading researcher in the field of self-powered electronic skin (e-skin) and energy harvesting systems, with a particular focus on hybrid triboelectric and piezoelectric nanogenerators. His most-cited work, a 2022 study on self-powered hybrid triboelectric–piezoelectric e-skin based on P(VDF-TrFE) electrospun nanofibers, has garnered 21 citations and represents a significant contribution to artificial sensory systems. This research addresses a critical challenge in wearable electronics: developing flexible, self-powered sensors that can mimic human skin’s sensory capabilities. Ra’s major contribution lies in integrating two energy conversion mechanisms—triboelectric and piezoelectric effects—into a single nanofiber-based platform, enabling both high sensitivity and self-powered operation for detecting human movements. His work has implications for prosthetics, human-machine interfaces, and healthcare monitoring. With a growing citation impact, Ra is establishing himself as an innovator in nanogenerator technology and soft electronics, pushing the boundaries of how flexible devices can autonomously sense and interact with their environment.
