Abstract The emergence of ionotronic materials has substantially extended the applications artificial skins by allowing intimate interfaces between electronics and biological/bionic surfaces toward achieving improved sensing communication with surrounding stimuli. However, are intrinsically temperature dependent, since water molecules play crucial roles in regulating both mechanical ionic conductivity materials. Hence, most will fail at temperatures below 0 °C. In this study, a highly...

Protein-based adhesives have gained considerable interest, due to their unique ecofriendliness and abundant functional groups.
