The invention discloses a wound damage state monitoring device based on a flexible breathable hydrogel film. A CNTs/graphene/GelMA electrospinning membrane in a dry state and a wet state is used, the CNTs/graphene/GelMA electrospinning membrane is packaged through a breathable membrane and then serves as a dual-functional sensor for wound exudate sensing and strain sensing, the sensor makes direct contact with a wound, and the tissue fluid exudate volume and wound deformation at the wound can be converted into electric signals through a voltage division circuit, and the electric signals can be detected by a portable oscilloscope to realize accurate and real-time monitoring of wound damage. 本发明公开了一种基于柔性透气水凝胶膜的伤口破损状态监测装置。使用干、湿两种状态的CNTs/石墨烯/GelMA电纺丝膜，并经过透气膜封装后作为用于伤口处渗出液传感、应变传感的双功能传感器，传感器与伤口直接接触，可以将伤口处的组织液渗出体积和伤口形变经分压电路转化为电信号，通过便携式示波器检测该电信号即可实现对伤口破损情况进行准确、实时的监测。
