From the lab to the field: Self-stratifying microbial fuel cells stacks directly powering lights (2020)
Journal Article

The microbial fuel cell (MFC) technology relies on energy storage and harvesting circuitry to deliver stable power outputs. This increases costs, and for wider deployment into society, these should be kept minimal. The present study reports how a MFC...

Response of ceramic microbial fuel cells to direct anodic airflow and novel hydrogel cathodes (2019)
Journal Article

© 2019 The Authors The presence of air in the anode chamber of microbial fuel cells (MFCs)might be unavoidable in some applications. This study purposely exposed the anodic biofilm to air for sustained cycles using ceramic cylindrical MFCs. A method...

Passive feeding in paper-based microbial fuel cells (2018)
Journal Article

Microbial fuel cells (MFCs) are often constructed using materials such as plastic that can be hazardous to the environment. Building MFCs from paper is a sustainable option, making the fuel cells lightweight and easy to carry. Transported in the bott... Read More about Passive feeding in paper-based microbial fuel cells.

Eating, drinking, living, dying and decaying soft robots (2016)
Presentation / Conference Contribution

Soft robotics opens up a whole range of possibilities that go far beyond conventional rigid and electromagnetic robotics. New smart materials and new design and modelling methodologies mean we can start to replicate the operations and functionalities...

The dawn of biodegradable robots (2016)
Journal Article

Robotics is a field that is not normally associated with green technology or sustainability. Robots are generally constructed using materials that are non-biodegradable, toxic and expensive. These factors can limit the potential uses that an artifici... Read More about The dawn of biodegradable robots.

Here today, gone tomorrow: Biodegradable soft robots (2016)
Presentation / Conference Contribution

© 2016 SPIE. One of the greatest challenges to modern technologies is what to do with them when they go irreparably wrong or come to the end of their productive lives. The convention, since the development of modern civilisation, is to discard a brok... Read More about Here today, gone tomorrow: Biodegradable soft robots.

Biodegradable and edible gelatine actuators for use as artificial muscles (2014)
Presentation / Conference Contribution

The expense and use of non-recyclable materials often requires the retrieval and recovery of exploratory robots. Therefore, conventional materials such as plastics and metals in robotics can be limiting. For applications such as environmental monitor...

Towards disposable microbial fuel cells: Natural rubber glove membranes (2013)
Presentation / Conference Contribution

Copyright © 2013 Delta Energy and Environment. Natural rubber from laboratory gloves (GNR) was compared to cation exchange membrane (CEM) in microbial fuel cells (MFC). GNR-MFCs produced an immediate working voltage (50mV) indicating the availability... Read More about Towards disposable microbial fuel cells: Natural rubber glove membranes.

Investigating a cascade of seven hydraulically connected microbial fuel cells (2012)
Journal Article

Seven miniature microbial fuel cells (MFCs) were hydraulically linked in sequence and operated in continuous-flow (cascade). Power output and treatment efficiency were investigated using varying organic loads, flow-rates and electrical configurations...

Investigating the effects of fluidic connection between microbial fuel cells (2011)
Journal Article

Microbial fuel cells (MFCs) can 'treat' wastewater but individually are thermodynamically restricted. Scale-up might, therefore, require a plurality of units operating in a stack which could introduce losses simply through fluidic connections. Experi...

The overshoot phenomenon as a function of internal resistance in microbial fuel cells (2011)
Journal Article

A method for assessing the performance of microbial fuel cells (MFCs) is the polarisation sweep where different external resistances are applied at set intervals (sample rates). The resulting power curves often exhibit an overshoot where both power a... Read More about The overshoot phenomenon as a function of internal resistance in microbial fuel cells.
