Abstract:

I shall describe principles and examples for using analog and bio-inspired computation for creating ultra-low-power wireless electronics for the deaf, blind, paralyzed, and in other bio-signal sensing or stimulating applications. Such techniques can yield more than order-of-magnitude power reductions while maintaining high levels of robustness to several sources of noise. I shall provide examples from systems built in my lab for bionic ear processors for the deaf, brain-machine interfaces for the blind and paralyzed, and in body sensor networks for patient monitoring.

Nature is a great circuit designer. She has innovated circuits in the biochemical, biomechanical, and bioelectronic domains that operate very robustly with highly imprecise parts and with incredibly low levels of power. I shall outline examples of how bio-inspired circuits and architectures have led to and are leading to novel architectures in sensing and computing, e.g., in ear-inspired radios, in architectures for improving operation in noise, in ultra-low-power signal-to-symbol conversion, and in hybrid analog-digital architectures that model computations within cells. Thus, we can mine the intellectual resources of nature to create devices useful to man just as we have mined her physical resources in the past. Such mining will require us to combine inspiration with perspiration and to understand how nature works with insight.
