About

Lijie Duan is a materials scientist and biomedical engineer whose research sits at the cutting edge of smart materials, flexible electronics, and biomimetic hydrogel design. His work is primarily focused on developing advanced hydrogel systems that mimic the mechanical and sensory properties of human skin, with significant applications in wearable sensors, health monitoring, soft robotics, and human–machine interfaces. Duan's most celebrated contribution is his development of bioinspired dynamic cross-linking hydrogels that replicate skin-like strain and pressure sensing behaviors — a landmark 2019 study that has garnered over 266 citations and demonstrated that synthetic materials can authentically emulate biological tissue in both function and feel. Expanding on this theme, he pioneered nucleotide-regulated hydrogels capable of remarkable toughness and rapid self-recovery, enabling durable, high-sensitivity sensors that withstand repeated mechanical stress — a persistent challenge in the field. His work on nucleobase-tackified adhesive gels further pushed boundaries, achieving robust adhesion across both polar and nonpolar solvents with over 120 citations recognizing its impact. Collectively, Duan's publications reflect a coherent and impactful research vision: transforming biological inspiration into practical, resilient smart materials that advance the future of flexible electronics and wearable biomedical devices.
