In this study, we prepared a mechanically tough and stretchable soft strain sensor that made by conducting double network hydrogel microfibers. They are prepared by combining poly(acrylamide)/alginate as a double network hydrogel and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) as a conducting polymer. The microfibers were formed by using microfluidic devices comprising co-axial aligned micro capillaries. The prepared conducting microfibers were highly stretchable as long as 5 times, which is achieved by double network structure of the covalent and ionic crosslinking network. It also exhibit the fast resistance change in proportional to the strain through connect/disconnect of PEDOT:PSS domains. The prepared microfibers are applied to the soft strain sensors, can detect human body motion. |
