▎ 摘　　要

NOVELTY - The device comprises a sensor main body that is provided with a vertical type graphene sensitive element (1), a stretchable polymer composite material substrate, a fixing clamp (3), a dislocation wiring terminal (4) and a connector. The vertical type graphite sensitive element is located on the stretchable polymer composite material base layer (2). The protective device is provided with an outer shell and an inner shell. The inner shell is connected with the outer shell. USE - Upright type graphene wireless sensing device for monitoring concrete crack during bridge construction, housing construction, and subway construction in a modern city. ADVANTAGE - The vertical type graphene wireless sensing device has high precision, large range, better than two-dimensional plane graphene can effectively concrete the structure crack for a long time. The structure is simple, the setting is reasonable, and the use is convenient. The sharp thorn of the edge of the crack is convenient to clean the alcohol-taking roller to form cleaning in time, convenient for adhesion of the sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an upright type graphene wireless sensing device for monitoring concrete crack. 1Vertical type graphene sensitive element 2Stretchable polymer composite material base layer 3Fixing clamp 4Protecting misplacement wiring terminal
