Research of Flexible Sensors Based on Multilayer Graphene Films
In order to explore new sensing materials and technologies in the field of structural monitoring,a flexible sensor with multilayer graphene film as a sensitive material was studied to sense the strain and impact force signals of structures.Based on the properties of similar triangles,a calibration experiment in the large strain range of the flexible sensor was designed,and the strain monitoring results of the flexible sensor and the resistance strain gauge were compared through the cantilever steel beam ex-periment.In addition,a sand impact test platform was built to realize impact response to different falling heights of sand.The ex-perimental results show that the flexible sensor has the ability of monitoring large deformation,can replace the resistance strain gauge to measure the structural strain,and can be used to measure the impact force of sand particles,and has a wide application prospect in the field of structural monitoring.
