About

Yihui Yuan is a leading researcher in stimuli-responsive polymer materials and soft robotics, with a focus on harnessing the Marangoni effect for energy conversion and actuation. Their pioneering work on Marangoni effect-driven motion has opened new pathways for miniature robots and electricity generation on water surfaces, as demonstrated in their highly cited 2017 study (50 citations). Yuan introduced a novel mechanism where organic solvent-swollen gels, specifically polyvinylidene fluoride/dimethyl formamide (PVDF/DMF) droplets, convert chemical-free energy into dynamic motion and electrical power. In a subsequent breakthrough, Yuan developed a highly stretchable, tough polymer actuator driven by acetone vapors, capable of stretching to 600% of its original length—a critical advancement for wearable electronics and soft robotics. This work, published in 2018, showcases Yuan’s ability to engineer robust, micropatterned single-layered actuators that maintain performance under extreme deformation. With a growing citation impact, Yuan’s contributions are shaping the future of autonomous soft machines and sustainable energy harvesting, offering elegant solutions that merge materials science with practical, real-world applications.
