Electrospinning Machine| Breathable, antibacterial, and highlysensitive tribo-sensors using HOF embeddednanofibers for movements monitoring andinjury prevention

Donghua University Academician Zhu Meifang's Team in Nano Energy (IF 16.8): Breathable, Antibacterial, Highly Sensitive Triboelectric Sensor

Challenge: Physical activity is crucial for both physical and mental health, but improper exercise may cause serious injuries.

Approach: A research team led by Academician Zhu Meifang's group at Donghua University, including Associate Professor Xiang Hengxue and Researcher Cao Ran, developed a breathable, antibacterial, and sweat-proof triboelectric sensor (BATS) for real-time body motion monitoring to reduce injury risks.

Innovation 1: BATS was fabricated by embedding hydrogen-bonded organic framework (HOF-101-F) into polyvinylidene fluoride (PVDF) nanofibers. When integrated with logic circuits, the BATS system provides immediate warnings for improper movements or gestures, helping prevent injuries.

Innovation 2: BATS demonstrates excellent antibacterial properties. The photoactive HOF-101-F generates singlet oxygen (1O2), achieving over 90% antibacterial efficacy against E. coli and inhibiting microbial growth under sweaty conditions during physical activities.

Innovation 3: Compared to pure PVDF, incorporating HOF-101-F enhanced BATS's electrical output by 250%. The fully fiber-based, breathable BATS can be seamlessly integrated into sportswear.
