Conductive hydrogels with core–shell structures to realize super-stretchable, highly sensitive, anti-dehydrating, non-freezing and self-adhesive capabilities

The hydrophobic layer endowed excellent anti-drying capability (84 ± 0.45%weight retention after 7 days). The hydrogel was also ultra stretchable (strain = 5200%), self-adhesive, highly sensitive (GF = 6.41), and anti-freezing (−20 °C).
