Microbial fuel cells (MFCs) that generate electricity from a broad diversity of biomass and organic substrates through microbial metabolism have attracted considerable research interest as an alternative clean energy technology and energy-efficient wastewater treatment method. Despite encouraging successes and auspicious pilot-scale experiments of the MFCs, increasing doubts about their viability for practical large-scale applications are being raised. Low performance, expensive core parts and materials, energy-intensive operation, and scaling bottlenecks question a sustainable development. Instead, special MFCs for low-power battery-reliant devices might be more applicable and potentially realizable. Such bacteria-powered biobatteries would enable i) a truly stand-alone low-cost device platform suitable for use in disposable or resource-limited settings, ii) simple, on-demand power generation within a programmed period of time, and iii) a seamlessly integrated power source for the emerging smart textile applications. The biobattery would be an excellent power solution for small-scale, on-demand, disposable, and flexible electronics.
This dissertation is organized in four parts. Part I consists of Chapter 1, that set the stage for the whole dissertation which is the MFC-based biobatteries with a critical point of view on their limitations as practical power source. Then, a brief introduction to the flexible and stretchable electronics is provided, followed by the challenges on the power sources to energize these electronics. In the end of Chapter 1, the rationale on using flexible biobatteries to power small-scale stand-alone electronics is given. Part II presents the flexible paper-based biobatteries and consists of Chapters 2 and 3. Part III focuses on the flexible and stretchable yarn-based biobatteries and consists of Chapter 4. Part IV gives a comprehensive summary and outlook for the biobatteries which consists of Chapter 5.
