| Resonant sensor has good repeatability, resolution and stability. All-fiber resonant micro sensor has the advantages of micro-nano structure and optical fiber sensing characteristics. Graphene, as a new material discovered in recent years, has good thermodynamic and mechanical properties and can be used as a sensitive element in resonant sensors. A graphene resonant pressure sensor based on optical fiber F-P structure is presented in this paper. It has the advantages of both micro-mechanical sensor and optical fiber resonator. It has high resonant frequency. It shows good performance in pressure measurement experiment. The maximum pressure sensitivity can reach 2.93 Hz/Pa. It has important application value. |
