About

Haijun Feng is pioneering the frontier of soft robotics and smart materials, with a focus on liquid crystal elastomers (LCEs) that can move, adapt, and respond autonomously. His research centers on harnessing self-oscillation phenomena—inspired by nature—to create soft robots capable of sustained, designable locomotion with minimal external control. In his highly cited 2024 work (90 citations), Feng demonstrates a multimodal autonomous LCE soft robot that converts internal oscillations into directed movement, opening new pathways for untethered, self-regulating machines. Complementing this, his 2023 study (54 citations) introduces a breakthrough method for programming multiple actuation onsets within a single LCE by isomerizing network topology, enabling post-synthesis tunability of actuation temperature—a feat previously unattainable. This dual capability to both initiate and regulate motion on demand marks a significant leap in material intelligence. Feng’s contributions are shaping the next generation of adaptive soft systems, with implications for biomedical devices, environmental sensors, and autonomous robotics. His work stands at the intersection of materials chemistry and mechanical design, offering elegant solutions to the challenge of building machines that move like living organisms.
