About

Peiyi Li is a pioneering researcher at the intersection of soft robotics, bioinspired materials, and wearable electronics. Their work is unified by a focus on developing intelligent, stimuli-responsive hydrogels that can sense, actuate, and communicate in challenging environments. Li’s most influential contribution is a photothermal-responsive hydrogel actuator with shape-memory capabilities, directly inspired by the adaptive locomotion of sea cucumbers—a breakthrough that has garnered 27 citations since 2025 and promises to redefine soft robotic locomotion. They have also engineered a soft, stretchable, conductive hydrogel using liquid metal for highly accurate facial expression monitoring (20 citations), demonstrating exceptional electrical conductivity and mechanical compliance. Further notable achievements include a polydopamine-triggered adhesive hydrogel enabling Morse code communication in polar conditions, and a thermal-sensitive artificial ionic skin with self-healing properties for environmental stability. Beyond materials science, Li has contributed to digital health interventions for pediatric perioperative care. With a rapidly growing body of work that seamlessly blends fundamental materials chemistry with practical biomedical and robotic applications, Peiyi Li is establishing themselves as a leading voice in the next generation of adaptive, intelligent soft matter.
