“…Activating MFCs via spore germination has been used recently to pave the way for MFC-based batteries. [29] However, the achieved results only demonstrated the operating principle with a slow and hard-toregulate activation process without a direct and useful application. Here, we integrated this mechanism into a practical application achieving a multi-cell MFC where each cell can supply up to 110 μW cm −2 and takes only 18 min for the device to activate completely.…”

Single‐use electrical systems represent the future of multiple fields such as diagnostic medical technologies, environmental studies, and biofuel manufacturing with significant advantages over conventional unrecyclable bulky systems that are partly disposable at best. Single‐use systems require miniaturized bio‐friendly energy sources that meet the recyclability or reusability requirement of the application without creating toxic waste. Herein, a storable, scalable, and single‐use electronics‐compatible bio‐battery that is designed and fabricated using completely reusable and recyclable components is developed. The battery is a dual‐in‐line package microbial fuel cell (DIP‐MFC) that can be activated on demand via the introduction of moisture through the anodic fluid chamber. The battery incorporates dormant bacteria cells on an abiotic stainless steel mesh that serves as the anode that attracts electrons being transferred from the biocatalyst. The DIP‐MFC uses the infestation of bacterial biofilm on a conductive anode to harness electrons and deliver electricity to selected circuit pins. A single DIP‐MFC continuously operates for 140 min with a maximum open circuit voltage of 0.55 V, which can be stacked and connected to match the power requirements of targeted electronics. The DIP nature of the proposed bio‐battery allows for simple integration of the MFC on conventional electronics boards through conductive pins.

“…[4,19] Very recently, our group revolutionized the shelf-life of the MFC by using endospores as a dormant biocatalyst and successfully demonstrated its power generation by germinating the spores with specific nutrients. [27,28] All solid-phase MFC components and the hygroscopic nature of paper allowed simple power generation with water introduction or moisture harvested from the air. [28] If sufficient power can be produced, spore-forming MFCs will become the best-fit power source for the manufacture and operation of papertronic systems because they exploit the robust nature of bacterial spores for processing and prolonged storage.…”

[28] If sufficient power can be produced, spore-forming MFCs will become the best-fit power source for the manufacture and operation of papertronic systems because they exploit the robust nature of bacterial spores for processing and prolonged storage. Existing paperbased MFCs are very limited by their low power (≈1 μW cm 2 ) and short shelf-life (≈a couple of hours), which renders them insufficient for practical applications.…”

Transient electronics, which can operate only for short‐lived applications and then be eco‐friendly disintegrated, create opportunities in environmental sensing, healthcare, and hardware security. Paper‐based electronics, or papertronics, recently have rapidly advanced the physically transient device platform because paper as a foundation offers an environmentally sustainable and cost‐effective option for those increasingly pervasive and fast‐updated single‐use applications. Paper‐based power supplies are indispensable to realize a fully papertronic paradigm and are a critical enabler of environmentally benign power solutions. Microbial fuel cells (MFCs) hold great potential as power sources for such green papertronic applications. This work reports the design, operation, and optimization of a high‐power papertronic MFC by biosynthesizing microbe‐mediated tin oxide nanoparticles (SnO2 NPs) on dormant Bacillus subtilis endospores. They form an electrical conduit that improves electron harvesting during the spore germination and power generation. The MFC is packaged in a sub‐microporous alginate to minimize the potential risk of bacteria leakage. Upon the introduction of water, the paper‐based MFC generates a significantly enhanced power density of 140 µW cm−2, which is more than two orders of magnitude greater than their previously reported counterparts. Six MFCs connected in series generate more than sufficient power to run an on‐chip, light‐emitting diode.
