A autonomous, wireless carbon nanotube strain sensor embedded in concrete for crack monitoring
Résumé
We describe the prototyping of a battery-powered, RFID-enabled carbon nanotube strain sensor for concrete strain and crack monitoring. A series of 10 prototypes has been embedded in a real structure. After a year it is still providing valuable information on the state of the structure. The final volume of the embedded module is 43cm3, the lowest volume reported to date in the field of embedded monitoring of concrete.
