About

Jian Chang is a materials scientist and energy researcher whose work sits at the intersection of flexible electronics and energy storage technology. Chang's most recognized contribution to the field is the 2020 paper "A Figure of Merit for Flexible Batteries," which has garnered 119 citations and represents a significant methodological advance in how researchers evaluate and compare flexible battery performance. Prior to this work, the field lacked a standardized framework for assessing the mechanical and electrochemical trade-offs inherent in flexible energy storage devices — a gap that Chang's figure of merit elegantly addressed. By providing the community with a unified metric, Chang enabled more rigorous benchmarking across diverse flexible battery architectures, accelerating both fundamental research and practical device development. This contribution has proven particularly timely given the explosive growth of wearable electronics, soft robotics, and implantable medical devices, all of which demand reliable, mechanically compliant power sources. Chang's work exemplifies how thoughtful theoretical frameworks can shape experimental priorities across an entire subfield, making it an essential reference for researchers designing next-generation flexible energy systems.
