About

Dr. Yaqiang Ji is advancing the frontiers of flexible electronics and micro-robotics through innovative laser-based fabrication and materials design. His primary research areas include flexible metal electrodes for human–machine interfaces and the development of biodegradable microswimmers for biomedical applications. In his highly cited 2022 work (38 citations), Dr. Ji introduced a femtosecond laser-activated metal deposition strategy that enables mask-free, low-cost patterning of flexible metal electrodes directly onto PDMS substrates—a critical breakthrough for next-generation wearable and implantable electronics. This method overcomes longstanding challenges in fabricating stretchable, conductive pathways without complex lithography. In parallel, his research on stop-flow lithography (2022, 4 citations) produced the first degradable hydrogel achiral crescent microswimmers, addressing the pressing need for transient microrobots that can safely degrade in biological environments after completing targeted tasks. By integrating degradability with precise shape control, Dr. Ji’s work paves the way for safer, more sustainable micro-robotic therapies. His contributions are shaping the future of soft, bio-integrated electronics and environmentally conscious micro-robotics.
