Wearable electronics have been extensively studied owing to their capability of undertaking continuous multi-task for daily needs. Meanwhile, lightweight, flexible, and wearable power sources that enable high-power and sustainable energy conversion from ambient resources (e.g. bodily fluids) have attracted attention. We propose a wearable and flexible textile-based biofuel cell using moisture management fabric (MMF) widely used in sportswear as a transport layer for sustainable and high-power energy harvesting. The reduction of PB-modified cathode is driven by the oxidation of glucose catalyzed by GOD-modified anode, and this enables a single-compartment structure where MMF acts as biofuel transport media. MMF made of polyester can naturally induce a continuous, high-speed flow which facilitates molecule transport for efficient chemical reactions without an additional pump. The resulting highly efficient power generation in MMF is explored and verified by comparing it with those of cotton and paper. Additionally, multi-stack biofuel cell in both parallel and series was successfully realized, and the open circuit voltage and maximum power reached 1.08 V and 80.2 μW, respectively. Integrated into a bandage and sportswear, a six-stack biofuel cell was able to generate sufficient electrical power from human sweat and turn on a sports watch directly. Owing to low-cost and scalable fabrication process, the proposed biofuel cell has great potential to be systematically integrated into clothes, and generate sufficient and sustainable electrical power for wearable electronics using biofuel (e.g. glucose, lactase) from various bodily fluids, like sweat and urine.

由于可穿戴电子设备能够满足日常需求的连续多任务处理能力，因此已被广泛研究。同时，轻巧，灵活且可穿戴的电源可实现从周围资源（例如，体液）引起了人们的关注。我们提出了一种使用可湿性和柔韧性的基于纺织的生物燃料电池，该电池使用了广泛用于运动服中的水分管理织物（MMF）作为可持续和大功率能量收集的传输层。PB修饰的阴极的还原是由GOD修饰的阳极催化的葡萄糖氧化驱动的，这使得单隔室结构成为了MMF充当生物燃料传输介质的地方。由聚酯制成的MMF可以自然地引起连续的高速流动，从而无需额外的泵即可促进分子运输，实现有效的化学反应。通过将其与棉花和纸张进行比较，探索并验证了MMF中产生的高效发电。此外，成功实现了并联和串联的多堆生物燃料电池，开路电压和最大功率分别达到1.08 V和80.2μW。六层生物燃料电池集成在绷带和运动服中，能够从人的汗液中产生足够的电能，并直接打开运动手表。由于低成本和可扩展的制造工艺，拟议的生物燃料电池具有很大的潜力，可以系统地集成到衣服中，并为使用生物燃料的可穿戴电子设备产生充足且可持续的电力（（例如葡萄糖，乳糖酶）来自各种体液，例如汗液和尿液。
