ABSTRACT: Conductive hydrogels had demonstrated significant prospect in the

field of wearable devices. However, hydrogels suffer from a huge limitation of

freezing when the temperature falls below zero. Here, a novel conductive

organohydrogel was developed by introducing polyelectrolytes and glycerol into

hydrogels. The gel exhibited excellent elongation, self-healing, and self-adhesive

performance for various materials. Moreover, the gel could withstand a low

temperature of ?20 °C for 24 h without freezing and still maintain good

conductivity and self-healing properties. As a result, the sample could be applied for

motion detection and signal transmission. For example, it can respond to finger

movements and transmit network signals like network cables. Therefore, it was

envisioned that the effective design strategy for conductive organohydrogels with

antifreezing, toughness, self-healing, and self-adhesive properties would provide wide

applications of flexible wearable devices.
