About

Subi Choi is a leading researcher in the field of bioinspired soft robotics and active materials, with a core focus on developing next-generation artificial muscles and programmable shape-morphing polymers. Her major contributions center on overcoming the performance trade-offs that have historically limited artificial muscle technologies. In her highly influential 2022 work, "Human-muscle-inspired single fibre actuator with reversible percolation," which has garnered 215 citations, Choi introduced a novel actuator design that achieves an unprecedented combination of high strain, stress, energy density, and mechanical strength—mimicking the sophisticated performance of human muscle. This breakthrough addresses a critical bottleneck for practical robotics applications. Additionally, her 2020 paper on mechanically programmed liquid crystal elastomers (LCEs) demonstrates a versatile two-step photocrosslinking method to create complex 2D and 3D shape transformations at both macro- and microscales. With 38 citations, this work provides a powerful platform for designing adaptive structures. Choi’s research is distinguished by its elegant integration of materials chemistry and mechanical engineering, directly enabling more lifelike and capable soft robots.
