Health Monitoring of Cement-Based Materials via Graphene Conductive Skin

As the complexity of building structures increases, traditional monitoring methods face significant challenges. To address this issue, a novel health monitoring technology for cement-based materials is proposed to achieve non-destructive, real-time monitoring of structures. This method is easy to operate, requires minimal maintenance, and is suitable for health monitoring of existing structures. By using conductive skin made from graphene-based conductive carbon ink, and covering the surface of structural components with it, along with the analysis of resistance, strain, and load data, the formation and development of cracks can be effectively monitored. The experimental results show that the crack monitoring sensitivity of a standard 0.5mm-thick conductive skin can reach 206.963Ω/mm, and the resistance variation of the conductive skin can effectively detect crack propagation with excellent monitoring sensitivity.
