'Wet' computing system aims to mimic brain processes
Researchers at the University of Southampton are embarking on a project to develop a new kind of information processing technology inspired by the chemical processes in living systems.
The project has just received €1.8 million from the European Union’s Future and Emerging Technologies (FET) Proactive Initiatives.
Dr Maurits de Planque and Dr Klaus-Peter Zauner at the University’s School of Electronics and Computer Science (ECS) will adapt brain processes to a 'wet' information processing scenario by setting up chemicals in a tube which behave like the transistors in a computer chip.
"What we are developing here is a very crude, minimal liquid brain and the final computer will be ‘wet’ just like our brain," said Dr Zauner. "People realise now that the best information processes we have are in our heads and as we are increasingly finding that silicon has its limitations in terms of information processing, we need to explore other approaches, which is exactly what we are doing here."
The project will run for three years and involves three complementary objectives.
The first is to engineer lipid-coated water droplets, inspired by biological cells, containing an excitable chemical medium and then to connect the droplets into networks in which they can communicate through chemical signals.
The second is to design information-processing architectures based on the droplets and to demonstrate purposeful information processing in droplet architectures.
The third is to establish and explore the potential and limitations of droplet architectures.
“Our system will copy some key features of neuronal pathways in the brain and will be capable of excitation, self-repair and self-assembly,” said Dr de Planque.
