摘要
Soft and flexible materials have recently attracted great attention as a sensing layer in the fields of health monitoring, human-machine interface, internet of things and soft robotics. Owing to its unique merits such as excellent flexibility, outstanding biocompatibility and superb sensitivity, conductive hydrogel can meet the need of soft sensing materials in the fields above. However, nonlinear sensitivities under high strains affect the application in practice. Moreover, the free water in conductive hydrogel will freeze or dry under extreme environment, even slowly evaporating at room temperature. Current innovation researches have demonstrated some advanced measures to improve its shortcomings and fit the applications in special environment. This review provides an overview of current flexible electronics based on conductive hydrogel for intelligent sensing and smart controlling. We sort and introduce the fabrication of conductive hydrogel according to different conductive materials. Furthermore, we focus on three classes of applications, including human-machine interfaces (HMIs), health monitoring and motion detection. At the end of the review, the still unresolved challenges are briefly summarized and novel directions for conductive hydrogel-based electronics are provided.
