About
Longfei Chang is a prominent researcher in the field of soft robotics and biomimetic actuator systems, with a particular focus on developing smart materials that convert multiple energy inputs — including light, electricity, and humidity — into controlled mechanical motion. His work centers on designing multistimuli-responsive soft actuators that replicate sophisticated biological behaviors, drawing inspiration from natural organisms to engineer next-generation robotic systems. Chang's most influential contributions include pioneering light-driven self-oscillating actuators capable of autonomous locomotion without external intervention, leveraging advanced nanomaterials such as carbon nanotubes, MXene (Ti₃C₂Tₓ), and black phosphorus heterostructures. His 2017 paper on electrically and sunlight-driven CNT bilayer actuators has garnered 285 citations, while his self-oscillating phototactic locomotion work from 2020 has accumulated over 200. Collectively, his top publications have amassed more than 1,100 citations, reflecting substantial influence across materials science and robotics communities. Beyond actuation, Chang has explored integrated energy harvesting, developing devices that simultaneously perform mechanical work and generate photoelectric power. His review on ionic electroactive polymers further demonstrates his breadth across bioinspired robotics. His research meaningfully advances the development of untethered, intelligent soft robotic systems with real-world applications in industrial, biomedical, and environmental domains.
