The fabrication and performance of a flexible and stretchable microbial fuel cell (MFC) monolithically integrated into a single sheet of textile substrate are reported. The single‐layer textile MFC uses Pseudomonas aeruginosa (PAO1) as a biocatalyst to produce a maximum power of 6.4 µW cm−2 and current density of 52 µA cm−2, which are substantially higher than previous textile‐MFCs and are similar to other flexible paper‐based MFCs. The textile MFC demonstrates a stable performance with repeated stretching and twisting cycles. The membrane‐less single‐chamber configuration drastically simplifies the fabrication and improves the performance of the MFC. A conductive and hydrophilic anode in a 3D fabric microchamber maximizes bacterial electricity generation from a liquid environment and a silver oxide/silver solid‐state cathode reduces cathodic overpotential for fast catalytic reaction. A simple batch fabrication approach simultaneously constructs 35 individual devices, which will revolutionize the mass production of textile MFCs. This stretchable and twistable power device printed directly onto a single textile substrate can establish a standardized platform for textile‐based biobatteries and will be potentially integrated into wearable electronics in the future.

灵活且可伸展的生物电池:无膜微生物燃料电池在单个纺织层中的单片集成

报告了柔性和可拉伸的微生物燃料电池(MFC)单片集成到单层纺织基材中的制造和性能。单层纺织品MFC使用铜绿假单胞菌(PAO1)作为生物催化剂,产生的最大功率为6.4 µW cm -2,电流密度为52 µA cm -2,它大大高于以前的纺织MFC,并且与其他基于纸张的柔性MFC相似。纺织品MFC在反复的拉伸和加捻循环中表现出稳定的性能。无膜单腔配置大大简化了制造过程并提高了MFC的性能。3D织物微腔室中的导电性和亲水性阳极可最大程度地提高液体环境中细菌的发电量,而氧化银/银固态阴极则可减少阴极超电势,从而实现快速的催化反应。一个简单的批生产方法可以同时构造35个单独的设备,这将彻底改变纺织品MFC的批量生产。
