About

Professor Gehan Amaratunga is a pioneering figure in advanced materials and nanoelectronics, whose work bridges fundamental physics with transformative device applications. His research spans iontronics, flexible electronics, and energy-efficient semiconductor technologies, with a focus on creating adaptive, mechanically robust systems. A standout contribution is his development of iontronic pressure sensors that overcome the limitations of traditional solid-state dielectrics—such as poor dielectric tunability and mechanical instability—by leveraging ionic dynamics for enhanced sensitivity and dynamic response. This work, highlighted in his 2026 paper with 5 citations, has direct implications for electronic skin, wearable health monitors, and soft robotics. Beyond this, Amaratunga’s broader impact is reflected in over 20,000 citations across his career, with seminal contributions to carbon nanotube field emission, power electronics, and neuromorphic computing. He has been recognized with prestigious awards, including the IEEE Edison Medal and a Royal Society Wolfson Research Merit Award, and his leadership as a professor at the University of Cambridge has shaped a generation of researchers. Amaratunga’s innovations continue to push the boundaries of flexible, intelligent electronics.
