纸基电子（papertronics）最近被认为是最令人兴奋的设备平台之一，因为它们具有灵活性，可持续性，环保性和低成本以及优异的机械，介电和流体特性。现在，创新的结构工程技术可以操纵纸张纤维素纤维的直径，平滑粗糙度并控制许多设备应用的透明度。有机、无机和生物实体的新型纸功能化技术使许多工程可能性成为可能，为下一代电子产品带来了革命性的纸电子学。在这些新功能的技术中，将电子细菌集成到纸中作为一种新的纸电子能源技术引起了相当大的兴趣。纸张具有独特的协同特性，包括有利于细菌生存的多孔和亲水环境，有利于细菌积累的高表面积，以及即使在资源有限的环境下也具有可持续性。在这项工作中，全面的分析和实验方法提供了一种新颖的，但现实的和可获得的能量来源，从细菌加载到纸上。该报告提供了革命性地激活生物电池并显着提高其保质期的新方法。此外，首次确保了所探索技术的实际功效，即使在资源有限的环境中也能按需产生能源。
Paper-based electronics (papertronics) are recently considered as one of the most exciting device platforms because of their flexibility, sustainability, eco-friendliness, and low cost as well as their excellent mechanical, dielectrical, and fluidic properties. Now, innovative structure engineering techniques can manipulate diameters of the cellulose fibers of paper, smoothing the roughness and controlling the transparency for numerous device applications. Novel functionalization techniques of paper with organic, inorganic, and biological entities enable many engineering possibilities, revolutionizing papertronics for the next generation of electronics. Among those techniques for new functionalities, integrating electric bacteria into paper has attracted considerable interest as a new energy technique for papertronics. Paper has unique synergistic characteristics including a porous and hydrophilic environment for bacterial viability, a high surface area for bacterial accumulation, and sustainability even in resource-limited settings. In this work, comprehensive analytical and experimental approaches to provide a novel but realistic and accessible power source from bacteria loaded into paper are pursued. This report provides new approaches to revolutionarily activate the biobattery and significantly improve its shelf life. Furthermore, for the first time the practical efficacy of the explored technique is ensured, generating on-demand energy even in resource-limited environments.
