Bio-inspired Circuits and Systems

The broad aim of the project is to develop novel analogue and mixed signal circuits for bio-inspired sensing systems. Our recent projects in this area include neuromorphic olfactory systems, wind sensing mechanisms to mimic those found in the cricket and bio-mimetic active cochlea. We are interested in developing novel interface circuits and sensor signal processing circuits for a variety of sensors used in neuromorphic systems. Examples include chemical sensors used for olfactory sensing, cantilever MEMS structures for bio-morphic wind sensing systems and active MEMS/CMOS based resonant gate transistor (RGT) microphone for cochlea.

In the active cochlea project, novel analogue circuit implementations of cochlea filters that mimic the characteristics of the biological cochlea have recently been developed. This PhD project sets out to develop multi-channel filter arrays combined with adaptive sensor control mechanisms and event based processing to deliver a novel cochlea front end for a neuromorphic processing system. The effectiveness of the sensory circuit may be tested in a range of acoustic environments at the acoustic labs of our collaborator at the University of Stirling. The small size and integrated electronics of the device, coupled with its internal signal processing will make it an attractive candidate as a front end to hearing aids and cochlea implants.
