About

Junlong Liao is a leading innovator at the intersection of advanced materials and wearable energy technology. His research focuses on two key areas: the design of 3D-printable photonic crystals and the development of self-powered, multifunctional electronic systems. Liao’s major contributions include pioneering the fabrication of colloidal photonic crystals via 3D printing, a breakthrough that enables precise, scalable production of structural color materials for sensors and displays. His most impactful work, "Piezoelectric-Driven Self-Powered Patterned Electrochromic Supercapacitor for Human Motion Energy Harvesting" (2018, 107 citations), demonstrates a fully integrated wearable device that simultaneously harvests mechanical energy from human motion, stores it, and visually indicates charge levels through electrochromic color changes. This innovation addresses the critical need for sustainable, miniaturized power sources in portable electronics. With his 2022 paper on 3D-printable photonic crystals already garnering 166 citations, Liao’s work is rapidly shaping the future of smart textiles and adaptive optics. His achievements exemplify a seamless blend of materials science and energy engineering, offering practical pathways toward truly autonomous wearable technologies.
