Document Type and Number:
Japanese Patent JP7057562
Kind Code:
B2
Abstract:
To provide a sensor device which can sensitively detect generation of an abnormality in a structure.SOLUTION: A sensor device 1 includes: a fiber-containing plastic plate 2 attached on a surface of concrete 100; a conductive metal foil 3 integrated with the fiber-containing plastic plate 2; and detection means 4 for detecting breakage of a metal foil 3. When the metal foil 3 is arranged across a cracking 101 in the concrete 100 and the cracking 101 is enlarged, the metal foil 3 is broken, which is detected by the detection means 4.SELECTED DRAWING: Figure 1
