There is an urgent need to develop a sustainable battery technology that is cheap, environmentally friendly, easy to fabricate and to dispose of, especially to tackle the world-wide increase in illegally dumped electronic wastes. Microbial biophotovoltaic (BPV) technology is a renewable bioenergy system currently being developed at the laboratory scale. It generates electricity from the photosynthetic metabolism of cyanobacteria and microalgae and exploits their ability to convert light energy into electrical current using water as the source of electrons. Innovative approaches are needed to solve scale-up issues such as cost, ease of fabrication (particularly the fabrication of the inorganic and biological (microbes) parts).In this talk, I will report the feasibility of using a simple commercial thermal-inkjet printer to fabricate a thin-film paper-based BPV cell consisting of a layer of cyanobacterial cells on top of a carbon nanotube conducting surface on plain copy paper. The digitally printed thin-film BPV system produced electricity both in the light and dark, with a maximum electrical power output of 0.38 mW m-2 in one system and the sustained electrical current production over 100 hours in another more fully printed system. I will address limitations and challenges as well possible applications in the area of printed bioelectronics.

Microbial biophotovoltaic cells exploit the ability of cyanobacteria and microalgae to convert light energy into electrical current using water as the source of electrons. Such bioelectrochemical systems have a clear advantage over more conventional microbial fuel cells which require the input of organic carbon for microbial growth. However, innovative approaches are needed to address scale-up issues associated with the fabrication of the inorganic (electrodes) and biological (microbe) parts of the biophotovoltaic device. Here we demonstrate the feasibility of using a simple commercial inkjet printer to fabricate a thin-film paper-based biophotovoltaic cell consisting of a layer of cyanobacterial cells on top of a carbon nanotube conducting surface. We show that these printed cyanobacteria are capable of generating a sustained electrical current both in the dark (as a ‘solar bio-battery’) and in response to light (as a ‘bio-solar-panel’) with potential applications in low-power devices.

This compilation of food design projects illustrates the possibilities new technologies provide to designers and the ways society perceives food.
Sawa M, 2016, An ecosophical intersection of design and algal biotechnology:Algaerium Bioprinter and Algae Printing, Shaping the Future 2017
The concept of ‘ecosophy’ by the French activist and psychoanalyst Félix Guattari sheds light on the root of ecological and sustainability issues in the intersections of natural environment, social relations and the mind of inhabitants. I will discuss an ecosophical intersection of design and algal biotechnology with my research-based biodesign outcomes: Algaerium Bioprinter (2013) and Algae Printing (2013-2015). The former is a concept design installation contextualising the latter a technology of the digital printing of living algal cells. Describing these outcomes, the first half of this talk illustrates domestication of algal biotechnology, a distinctive character that connects the three domains of ecosophy. I will show developed applications of the Algae Printing technology in the areas of food, energy and environment. Biodesign is expounded in terms of multifunctionality and semi-living systems along with ecosophical implications.The second half will explain the collaborative interdisciplinary process between the designer and algal scientists, which drove the conception of ideas and making of biodesign. The laboratory-based research practice will be described, demonstrating two-way collaboration and a co-inventor role of designer in scientific research.The talk will end by pointing towards an emerging shirt from ‘intellectual consumption’ to ‘utilitarian consumption’, from biodesign to bioindustry.
