Hydrogels have emerged as promising materials for flexible electronics due to their unique properties, such as high water content, softness, and biocompatibility. In this perspective, we provide an overview of the development of hydrogels for flexible electronics, with a focus on three key aspects: mechanical properties, interfacial adhesion, and conductivity. We discuss the principles of designing high-performance hydrogels and present representative examples of their potential applications in the field of flexible electronics for healthcare. Despite significant progress, several challenges remain, including improving the antifatigue capability, enhancing interfacial adhesion, and balancing water content in wet environments. Additionally, we highlight the importance of considering the hydrogel-cell interactions and the dynamic properties of hydrogels in future research. Looking ahead, the future of hydrogels in flexible electronics is promising, with exciting opportunities on the horizon, but continued investment in research and development is necessary to overcome the remaining challenges.
水凝胶因其高含水量、柔软性和生物相容性等独特性质，已成为柔性电子产品有前途的材料。在这个视角下，我们提供了水凝胶在柔性电子产品方面的发展概述，重点关注三个关键方面：机械性能、界面附着力和导电性。我们讨论了设计高性能水凝胶的原理，并介绍了它们在医疗保健领域柔性电子产品中潜在应用的代表性例子。尽管取得了重大进展，但仍存在一些挑战，包括提高抗疲劳能力、增强界面附着力以及平衡湿环境中的含水量。此外，我们强调了在未来研究中考虑水凝胶-细胞相互作用和水凝胶动态特性的重要性。展望未来，水凝胶在柔性电子产品中的前景一片光明，未来前景广阔，但需要继续投资于研究和开发，以克服现有的挑战。
