Strain sensors with high sensitivity and stretchability are the most promising for using as human motion detector. In this study, a mechanically tough and stretchable double-network (DN) conducting microfibers was produced by the combination of soft polyacrylamide and brittle calcium-alginate and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS). The variation in resistance response with the distortion of the conducting fibers based on the connection/partial disconnection of the PEDOT:PSS network. The changes in resistance are fully reversal and repeat over 10,000 times of 200% elongation. Further, this material system is flexible to be modified and we also established the conductivity with other materials such as silver nanowires (AgNWs). Through mechanical and electrical properties, the conducting microfibers are a potential candidate for stretchable strain sensor to detect human motion like bending of finger, running, and further the growth of a bamboo in garden. |
