Wet-resistant flexible electronics have gained impressive attention as
underwater wearable sensors, all-weather electronic skins, and implantable
bioelectrodes. However, fabricating a stable and nonswelling hydrogel-based
electronic device used in diverse liquid media is challenging and promising for the
progress of wet-resistance electronics. Herein, a solvent-resistant and tough hydrogel
conductor is successfully prepared and exhibits fatigue resistance, antifreezing
behavior, and nonswelling and wet-adhesion performances in organic and aqueous
solutions. Moreover, the hydrogels are utilized as all-weather wearable sensors
featuring high sensitivity, reliability, and wide sensing ranges for monitoring and
distinguishing various physiological signals and human motions. Furthermore, the
hydrogel sensors can even achieve accurate and stable mechanical sensing of
pressure, bending, and stretching in diverse solvents consisting of water, chloroform,
hexane, and dodecane. It is envisioned that the solvent-resistant and antifreezing hydrogel conductor can present promising
feasibility as all-weather electronic skins, intelligent sensors in solvents, and soft robots in various harsh liquid environments.
