Ultra-stretchable, self-recoverable, notch-insensitive, self-healable and adhesive hydrogel enabled by synergetic hydrogen and dipole–dipole crosslinking

This work presents a hydrogel with a dual crosslinked network of hydrogen bonds and dipole–dipole interactions, achieving 9000% stretchability, self-healing, adhesion and conductivity, making it ideal for wearable sensors and bioelectronics.
