About

Zhi-Wen Cheng is a leading figure in the field of soft robotics and smart materials, with a particular focus on liquid crystal elastomers (LCEs) and their electro-driven actuation systems. His most celebrated contribution, the "Liquid Crystal Elastomer Electric Locomotives" (2020, 110 citations), introduced a groundbreaking bilayered LCE/carbon black actuator that mimics biological locomotion. By integrating a U-shaped conductive track, Cheng demonstrated the first fully electro-driven, untethered cylindrical actuator capable of continuous, self-sustained motion—a pivotal step toward autonomous soft robots. This work not only achieved record-breaking actuation speeds for LCE-based devices but also established a new paradigm for energy-efficient, wire-free soft robotics. Beyond this flagship study, Cheng’s research has advanced the understanding of anisotropic deformation in stimuli-responsive polymers, with his publications collectively garnering over 500 citations. His innovative actuator designs have been recognized with multiple best paper awards and have inspired follow-up work in wearable haptics and micro-robotics. For students and researchers, Cheng’s work exemplifies how clever material engineering can transform fundamental polymer physics into functional, real-world locomotion systems.
