Inside Front Cover: The cover image depicts a close-up view of a wrinkle morphology 3D substrate-based conducting polymer hydrogel elastomer. This novel design, detailed in the article with doi:10.1002/idm2.12161, addresses the limitations of traditional conducting polymer hydrogels, particularly their brittleness and viscoelasticity. By utilizing digital light processing (DLP) technology and in-situ polymerization, an interconnection network hydrogel is formed, resulting in a material with reduced viscoelasticity, quick response time, low hysteresis, and stable cyclic performance. The wrinkle morphology effectively enhances the elastomer's flexibility and geometric freedom, while the 3D gradient structure boosts its sensitivity, positioning this material as a promising candidate for flexible sensor applications.
