Assistant Professor of Mechanical Engineering and Materials Science
The Ni group aims to realize human-oriented materials intelligence through the combination of soft electronics and digital metamaterials—the materials can sense human signals, transform and adapt their functional properties according to human actions or status. The technical approach embraces epidermal electronics for advanced sensing of body mechanics, and micro/nanomechanics for closed-loop programmable matter. Our research focuses on creating digital-physical interfaces for dynamic control over materials properties via a full spectrum of mechanical and acoustic processes.
