Effects of flow-rate, inoculum and time on the internal resistance of microbial fuel cells (2010)
Journal Article

To process large volumes of wastewater, microbial fuel cells (MFCs) would require anodophilic bacteria preferably operating at high flow-rates. The effect of flow-rate on different microbial consortia was examined during anodic biofilm development, u...

Optimization of bio-inspired multi-segment IPMC cilia (2010)
Presentation / Conference Contribution

In nature, unidirectional fluid flows are often induced at micro-scales by cilia and related organelles. A controllable unidirectional flow is beneficial at these scales for a range of novel robotic and medical applications, whether the flow is used...

A hybrid microbial dielectric elastomer generator for autonomous robots (2010)
Presentation / Conference Contribution

We are developing a hybrid Dielectric Elastomer Generator (DEG)-Microbial Fuel Cell (MFC) energy harvester. The system is for EcoBot, an Autonomous Robot (AR) that currently uses its MFCs to extract electrical energy from biomass, in the form of flie...

Improved energy output levels from small-scale Microbial Fuel Cells (2010)
Journal Article

This study reports on the findings from the investigation into small-scale (6.25mL) MFCs, connected together as a network of multiple units. The MFCs contained unmodified (no catalyst) carbon fibre electrodes and for initial and later experiments, a... Read More about Improved energy output levels from small-scale Microbial Fuel Cells.

Artificial symbiosis in EcoBots (2009)
Book Chapter

Truly autonomous robotic systems will be required to abstract energy from the environment in order to function. Energetic autonomy refers to the ability of an agent, to maintain itself in a viable state for long periods of time. Its behaviour must be... Read More about Artificial symbiosis in EcoBots.

Landfill leachate treatment with microbial fuel cells; scale-up through plurality (2009)
Journal Article

Three Microbial Fuel Cells (MFCs) were fluidically connected in series, with a single feed-line going into the 1st column through the 2nd column and finally as a single outflow coming from the 3rd column. Provision was also made for re-circulation in... Read More about Landfill leachate treatment with microbial fuel cells; scale-up through plurality.

Electricity from landfill leachate using microbial fuel cells: Comparison with a biological aerated filter (2009)
Journal Article

Four experimental columns were employed in this study to investigate their performance under wastewater treatment conditions. One column was set-up as a biological aerated filter and the remaining three were set-up as microbial fuel cells (MFCs), two...

Biological computing using perfusion anodophile biofilm electrodes (PABE) (2008)
Journal Article

This paper presents a theoretical approach to biological computing, using biofilm electrodes by illustrating a simplified Pavlovian learning model. The theory behind this approach was based on empirical data produced from a prototype version of these... Read More about Biological computing using perfusion anodophile biofilm electrodes (PABE).

Microbial fuel cells based on carbon veil electrodes: Stack configuration and scalability (2008)
Journal Article

The aim of this study was to compare the performance of three different sizes of microbial fuel cell (MFC) when operated under continuous flow conditions using acetate as the fuel substrate and show how small-scale multiple units may be best configur...

Artificial gills for robots: MFC behaviour in water (2007)
Presentation / Conference Contribution

This paper reports on the first stage in developing microbial fuel cells (MFCs) which can operate underwater by utilizing dissolved oxygen. In this context, the cathodic half-cell is likened to an artificial gill. Such an underwater power generator h... Read More about Artificial gills for robots: MFC behaviour in water.

Energetically autonomous robots: Food for thought (2006)
Journal Article

This paper reports on the robot EcoBot-II, which is designed to power itself solely by converting unrefined insect biomass into useful energy using on-board microbial fuel cells with oxygen cathodes. In bench experiments different 'fuels' (sugar, fru... Read More about Energetically autonomous robots: Food for thought.

EcoBot-II: An artificial agent with a natural metabolism (2005)
Journal Article

In this paper we report the development of the robot EcoBot-II, which exhibits a primitive form of artificial symbiosis. Microbial Fuel Cells (MFCs) were used as the onboard energy supply, which consisted of bacterial cultures from sewage sludge and...
