Hydrogels for Flexible Electronics

Hydrogelshave emerged as promising materials for flexible electronicsdue to their unique properties, such as high water content, softness,and biocompatibility. In this perspective, we provide an overviewof the development of hydrogels for flexible electronics, with a focuson three key aspects: mechanical properties, interfacial adhesion,and conductivity. We discuss the principles of designing high-performancehydrogels and present representative examples of their potential applicationsin the field of flexible electronics for healthcare. Despite significantprogress, several challenges remain, including improving the antifatiguecapability, enhancing interfacial adhesion, and balancing water contentin wet environments. Additionally, we highlight the importance ofconsidering the hydrogel-cell interactions and the dynamicproperties of hydrogels in future research. Looking ahead, the futureof hydrogels in flexible electronics is promising, with exciting opportunitieson the horizon, but continued investment in research and developmentis necessary to overcome the remaining challenges.
