The research will design and optimize a paper-based, bacteria-powered battery that can be integrated into paper-based microdevices to power on-board components. Paper has distinct advantages for fluid manipulation and analytical/clinical testing in applications such as point-of-care and point-of-use testing, particularly in low-resource settings. The proposed paper-based biobattery fuses the art of origami and the technology of Microbial Fuel Cells (MFCs) to generate power from microbial metabolism such that one drop of bacteria-containing liquid can deliver energy to next-generation paper-based systems. Every environment like soiled puddles or sewage has liquids that contain microorganisms that are sufficient for operating paper-based biobatteries. The proposed research therefore potentially has great social and economic impacts. It will enable low-cost diagnostic/analytical biosensors optimized for use under the most challenging environmental conditions. The project will address scientific education as the research outcomes will be shared through conferences and journals, and integrated into post-secondary courses as well as K-12 outreach.This research will advance the potential of paper battery to be fully integrated in paper-based microfluidic systems to power on-board components. The proposed origami technique will provide a series/parallel connection method for paper-based bacteria-powered batteries to produce a targeted power output that, upon adding a drop of bacterial-containing liquid will simply operate by capillary force through 3-D microfluidic pathways within the paper layers. For operation, the battery stack will be unfolded to expose all air-cathodes to the air, thereby maximizing their cathodic reactions. The goals of the research include gaining in-depth understanding of bacteria?s potential within a paper matrix and gauging bacterial ability to provide rapid electricity generation. The scope of investigation includes validating design footprints and bacterial combinations, when optimized will create a novel energy conversion technology based on paper. The potential benefits of bacteria-powered battery design include 1) a viable alternative power source for interfaced, paper-based analytical/diagnostic devices, 2) develop powered paper-based biosensing assays in easy-to-use packages, 3) increase fundamental understanding of bacterial transport and associated extracellular electron transfer mechanisms through a paper matrix, and 4) origami technique will establish and validate a platform precedent for battery stacks to be connected either in series or in parallel.

该研究将设计并优化一种基于纸张的细菌供电电池，这种电池可以集成到基于纸张的微设备中，为机载组件供电。在护理点和使用点测试等应用中，特别是在资源匮乏的环境中，纸张在流体操作和分析/临床测试方面具有明显的优势。这种纸基生物电池融合了折纸艺术和微生物燃料电池（mfc）技术，通过微生物代谢产生能量，这样一滴含有细菌的液体就可以为下一代纸基系统提供能量。每一个环境，比如肮脏的水坑或污水，都有含有微生物的液体，这些微生物足以让纸基生物电池工作。因此，拟议的研究可能具有巨大的社会和经济影响。它将使低成本的诊断/分析生物传感器能够在最具挑战性的环境条件下优化使用。该项目将解决科学教育问题，因为研究成果将通过会议和期刊分享，并纳入高等教育课程以及K-12外展。这项研究将推动纸电池在基于纸的微流体系统中充分集成的潜力，为车载组件供电。所提出的折纸技术将为基于纸张的细菌电池提供串联/并联连接方法，以产生目标功率输出，在添加一滴含有细菌的液体后，将通过毛细管力通过纸层内的三维微流控路径简单地操作。对于操作，电池堆将展开，使所有的空气阴极暴露在空气中，从而最大限度地发挥其阴极反应。这项研究的目标包括深入了解细菌。在纸基质内的S电位和测量细菌提供快速发电的能力。研究范围包括验证设计足迹和细菌组合，优化后将创建一种基于纸张的新型能量转换技术。细菌动力电池设计的潜在好处包括：1)为界面、纸质分析/诊断设备提供可行的替代电源；2)在易于使用的封装中开发纸质生物传感测试；3)通过纸质基质增加对细菌运输和相关细胞外电子转移机制的基本理解。4)折纸技术将为电池组串联或并联连接建立和验证一个平台先例。
