This review article discusses the recent progress in the development of environmentally tolerant conductive hydrogels (ETCHs) that possess anti-freezing, anti-drying, and anti-swelling properties. Traditional conductive hydrogels are limited by their high water content and hydrophilic network, which make them susceptible to freezing, drying, and swelling, thus restricting their application in harsh environments. To address these limitations, researchers have explored various strategies to enhance the environmental tolerance of conductive hydrogels. These strategies include incorporating salt solutions, using organic solvents, surface modification with hydrophobic elastomers, and employing multiple crosslinking mechanisms. The article highlights the effectiveness of these methods in improving the anti-freezing, anti-drying, and anti-swelling properties of conductive hydrogels. For instance, adding salt solutions like LiCl and NaCl can lower the freezing point and reduce water evaporation, while organic solvents such as DMSO and glycerol can replace water molecules, preventing freezing and drying. Surface modification with hydrophobic elastomers creates a barrier to prevent water loss, and multiple crosslinking mechanisms increase the crosslinking density, enhancing swelling resistance. The review also discusses the applications of ETCHs, including wearable sensors, bioelectrodes, soft robots, and wound dressings. These materials have shown great potential in human motion sensing, bioelectrode applications, and biomedical fields due to their ability to maintain functionality under extreme conditions. The article concludes by analyzing the current development status and limitations of different types of ETCHs, providing insights into future research directions and development prospects.This review article discusses the recent progress in the development of environmentally tolerant conductive hydrogels (ETCHs) that possess anti-freezing, anti-drying, and anti-swelling properties.
