Dielectric elastomer pump for artificial organisms (2011)
Journal Article
Rossiter, J. M., Bowers, A. E., Walters, P., & Ieropoulos, I. (2011). Dielectric elastomer pump for artificial organisms. Proceedings of SPIE, 7976, https://doi.org/10.1117/12.880440

This paper presents a bio-inspired, dielectric elastomer (DE) based tubular pumping unit, developed for eventual use as a component of an artificial digestive tract onboard a microbial fuel cell powered robot (EcoBot). The pump effects fluid displace... Read More about Dielectric elastomer pump for artificial organisms.

Investigating the effects of fluidic connection between microbial fuel cells (2011)
Journal Article
Winfield, J., Ieropoulos, I., Greenman, J., & Dennis, J. (2011). Investigating the effects of fluidic connection between microbial fuel cells. Bioprocess and Biosystems Engineering, 34(4), 477-484. https://doi.org/10.1007/s00449-010-0491-x

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
Winfield, J., Ieropoulos, I., Greenman, J., & Dennis, J. (2011). The overshoot phenomenon as a function of internal resistance in microbial fuel cells. Bioelectrochemistry, 81(1), 22-27. https://doi.org/10.1016/j.bioelechem.2011.01.001

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.

Power for robotic artificial muscles (2011)
Journal Article
O'Brien, B., Anderson, I. A., Ieropoulos, I., McKay, T., & Melhuish, C. (2011). Power for robotic artificial muscles. IEEE/ASME Transactions on Mechatronics, 16(1), 107-111. https://doi.org/10.1109/TMECH.2010.2090894

Artificial muscles based on the dielectric elastomer actuator (DEA) are an attractive technology for autonomous robotic systems. We are currently exploring their use on EcoBot (Ecological roBot), an autonomous robot being developed by Bristol Robotic... Read More about Power for robotic artificial muscles.
