Summary
Researchers at the University of Hong Kong (HKU) have developed a groundbreaking ionogel material that overcomes fundamental limitations in wearable medical technology. Led by Professor Tsui Lap-chi (徐立之) from the Department of Mechanical Engineering and first author Dr. Zhang He (張賀博士), the team utilized innovative micro-phase interface engineering to create a material that combines exceptional strength with skin-compatible softness. The research, published in the prestigious journal Science Advances, demonstrates that the ionogel can bear loads exceeding 5,000 times its own weight while retaining flexibility for comfortable skin contact .
Key Points
