Design of a very large chemical sensor system for mimicking biological olfaction
Biological olfaction involves processing information from up to 50 million receptors and understanding of the signal processing pathways involved is limited. Here we describe the design and fabrication of the largest array of chemical sensors in existence so far. It consists of 4096 organic semiconducting materials deposited on to a substrate of 4 cm.sq, is expandable up to 16664 sensors and is designed to mimic aspects of the array of sensors found in biological systems. The data acquired allows development and test of computational models of signal processing of olfactory information in the brain of mammals and insects.
