Abstract

In this research, we propose a method to detect the swell/shrink behavior of stimuli-responsive hydrogel by a strain sensor. The strain sensor is composed of single walled carbon nanotubes (SWCNTs) and a flexible sheet. By integrating the SWCNT strain sensor with a stimuli-responsible hydrogel, the swell/shrink behavior of the hydrogel can be simply sensed as an electrical resistance change of the SWCNT strain sensor. Our approach could contribute to simplify the stimulus detection and could be effective for the integration of high-sensitive chemical sensors with electrical devices.
