| Research Abstract |
A two-dimensional strain distribution sensor has been developed by applying multi-walled carbon nanotubes. The spatial resolution of the sensor was 50 mm, and its maximum gauge factor was 600. Dynamic strain was successfully measured at 1 kHz by using a micron wave at 99 GHz. These results clearly indicate that the developed sensor is effective for monitoring the strain on the surface of operating machines for assuring their integrity.
