The rapid development of flexible electronics has led to unprecedented social and economic improvements. But conventional power devices cannot adapt to the advances of flexible electronics. Triboelectric nanogenerators (TENGs) have been used as robust power sources to transform ambient mechanical energy into electricity, thus meeting the power requirements of flexible electronics. Hydrogels are widely used for soft bioelectronics owing to the decent stretchability and biocompatibility. This Review presents the recent progress in the use of hydrogels for TENGs and self-powered hydrogel bioelectronics, including hydrogel synthesis, hydrogel TENGs fabrication, and their applications in wearable electricity generation, self-powered active sensing, and therapeutics. Hydrogel-enabled TENGs are emerging as a novel form of soft bioelectronics. We provided a critical analysis of hydrogel TENGs and insights into future opportunities and directions of this rapidly evolving field. These advancements will push the boundaries of hydrogel bioelectronics and contribute to the development of personalized healthcare solutions.
柔性电子学的快速发展带来了前所未有的社会和经济进步。但传统的电源设备无法适应柔性电子学的发展。摩擦纳米发电机（TENGs）已被用作强大的电源，将环境机械能转化为电能，从而满足柔性电子学的电力需求。水凝胶因其良好的拉伸性和生物相容性而被广泛用于软生物电子学。本综述介绍了水凝胶在TENGs和自供电水凝胶生物电子学应用方面的最新进展，包括水凝胶合成、水凝胶TENGs制造及其在可穿戴发电、自供电有源传感和治疗方面的应用。基于水凝胶的TENGs正在成为一种新型的软生物电子学形式。我们对水凝胶TENGs进行了批判性分析，并对这个快速发展领域的未来机遇和方向进行了深入探讨。这些进展将推动水凝胶生物电子学的边界，并有助于个性化医疗解决方案的发展。
