Self-healable and recyclable polyurethane-polyaniline hydrogel toward flexible strain sensor

Flexible electronics have been extensively investigated in recent years because of their potential applications in artificial skin, soft robotics, energy storage, healthcare technology, etc. However, since the rigid and brittle nature of the conductive or semi-conductive materials, it's a huge challenge to project stretchable, self-healable and recyclable soft electronics to mimic skin. Herein, the interpenetrating and synergistic dual-network...
