我们使用折纸来创建一个紧凑、可扩展的三维(3-D)生物传感器堆栈，向便携式生物传感器提供按需能量。折叠允许具有预定义功能成分的二维(2-D)纸张形成9个3-D微生物燃料电池(MFC)，并在一个小而单一的单元(5.6 cm×5.6 cm)内串联它们。我们将生物催化剂铜绿假单胞菌PAO1加载到形成MFC的预定区域，并将其冷冻干燥以供长期储存。当冷冻干燥的细胞用容易获得的废水复水时，生物处理堆通过微生物代谢产生的最大功率和电流分别为20μW和25μA。这项工作建立了一种创新的战略，以彻底改变纸基MFC的制造、储存、操作和应用，这可能使能源即使在资源有限的情况下也能获得。
We use origami to create a compact, scalable three-dimensional (3-D) biobattery stack that delivers on-demand energy to the portable biosensors. Folding allows a two-dimensional (2-D) paper sheet possessing predefined functional components to form nine 3-D microbial fuel cells (MFCs), and connect them serially within a small and single unit (5.6 cm × 5.6 cm). We load the biocatalyst Pseudomonas aeruginosa PAO1 in predefined areas that form the MFCs, and freeze-dry them for long-term storage. The biobattery stack generates a maximum power and current of 20 μW and 25 μA, respectively, via microbial metabolism when the freeze-dried cells are rehydrated with readily available wastewater. This work establishes an innovative strategy to revolutionize the fabrication, storage, operation, and application of paper-based MFCs, which could potentially make energy available even in resource-limited settings.
