Abstract

The invention provides a multi-electrode sensing structure and a method thereof. The multi-electrode sensing structure comprises an FRP (Fiber Reinforce Plastic) rib, anchoring cylinders, a conductiveadhesive and an insulating adhesive, wherein two power supply electrodes are arranged on end faces of two ends of the FRP rib; FRP is divided into N sections and is disconnected and N-1 independent voltage electrodes are arranged; the anchoring cylinders are mounted on the independent voltage electrodes of sections; the anchoring cylinders are used for connecting the adjacent disconnected sections; the insulating adhesive is injected into the anchoring cylinders; the power supply electrodes are connected with a current input system; the independent voltage electrodes of the sections are connected with a voltage output system. When the FRP rib is subjected to an axial force, the FRP rib has axial deformation, the resistance of the FRP rib is changed and the output voltage is changed; the change value of the resistance is calculated through the change value of the current and the voltage, and is converted into section stress of the FRP rib; a stress level of the FRP rib is judged. According to the multi-electrode sensing structure provided by the invention, the FRP rib can express a self bearing force and a four-electrode circuit capable of eliminating contact resistance is formed;meanwhile, the stress state of the FRP rib can be accurately monitored in real time. The system is simple in structure, clear in principle and convenient to implement.

Description

technical field [0001] The invention belongs to the field of sensor research, and in particular relates to a multi-electrode sensing structure and a method thereof. The structure is a multi-electrode sensor structure indicating the existence and change of resistance, especially a sensor that can accurately identify the resistance change of the fiber conductive composite material so as to monitor the force of the material, and can be widely used in structure monitoring. Background technique [0002] At present, for materials with low conductivity, the DC two-terminal electrode method is generally used for resistance testing. Although there is a contact resistance between the electrode and the conductive composite material, its influence is small. However, for conductive composite materials with medium and high conductivity, the electrode contact resistance in the two-terminal electrode method has a significant impact on its conductivity test value. [0003] In order to elimi...
