Carbon nanotubes reinforced hydrogel as flexible strain sensor with high stretchability and mechanically toughness

Flexible strain sensors have attracted much attention for their applications in human–machine interactions and personal health monitoring. However, fabricating strain sensors based on hydrogels with high stretchability and tensile strength simultaneously still remains a challenge due to the intrinsic brittleness of conventional hydrogel. In this study, a conductive nanocomposite hydrogel comprised of oxidized multi-walled carbon nanotubes...
