Abstract
This paper describes the manufacturing method and the sensor properties of the CNT/PVDF composite material. The measurement principle is based on CNT/PVDF of electric resistance variation when it is subjected to a strain resulting from external loading. It was confirmed that resistance changed by the strain variation of the sensor. Moreover, the sensor characteristic confirmed the variation according to the ultrasonic agitation time. Experimental results show the statical and dynamical sensor properties of the CNT/PVDF composite.
