Flexible piezoresistive pressure sensors possess advantages such as mechanical flexibility, durability, and low production costs, making them valuable for applications in human motion monitoring, medical diagnostics, and electronic skin. However, in practical applications, these sensors still face numerous challenges, including long response times, low sensitivity, short lifespan, and limited functionality. This study investigates Ag@MXene-PVA composite double-network hydrogels and develops flexible piezoresistive sensors based on a polydimethylsiloxane (PDMS) substrate. The sensor exhibits high electrical conductivity and rapid response speed. The PDMS encapsulation not only maintains flexibility but also ensures resistance to damage under external forces, providing stable operational signals.

摘要

Flexible piezoresistive pressure sensors possess advantages such as mechanical flexibility, durability, and low production costs, making them valuable for applications in human motion monitoring, medical diagnostics, and electronic skin. However, in practical applications, these sensors still face numerous challenges, including long response times, low sensitivity, short lifespan, and limited functionality. This study investigates Ag@MXene-PVA composite double-network hydrogels and develops flexible piezoresistive sensors based on a polydimethylsiloxane (PDMS) substrate. The sensor exhibits high electrical conductivity and rapid response speed. The PDMS encapsulation not only maintains flexibility but also ensures resistance to damage under external forces, providing stable operational signals.
