Smart textiles for electricity generation are a superior energy solution with greatly improved convenience and comfort for wearable bioelectronics. However, maintaining the sustainability and stability of the power supply, though highly desirable, remains a great challenge. Here, we present a photo-rechargeable fabric with economically viable materials and scalable fabrication technologies. The fabric was able to constantly deliver electric power for 10 min at 0.1 mA after being charged for 1 min under the standard 1-sun condition. It can also work normally under twisted and watery circumstances and hold the stored energy for over 60 days without significant voltage loss. The photo-rechargeable fabric was demonstrated to power a body area sensor network for personalized healthcare.

用于发电的智能纺织品是一种卓越的能源解决方案，极大地改善了可穿戴生物电子产品的便利性和舒适性。但是，保持电源的可持续性和稳定性虽然是非常理想的，但仍然是一个巨大的挑战。在这里，我们介绍一种具有经济可行性的材料和可扩展的制造技术的可光充电织物。在标准的1阳光条件下充电1分钟后，该织物能够在0.1 mA的电流下持续提供10分钟的电能。它也可以在扭曲和潮湿的环境下正常工作，并将存储的能量保持60天以上，而不会出现明显的电压损失。可充电光的织物被证明可为人体区域传感器网络提供动力，以实现个性化医疗保健。
