The project aims at integrating into a functional prototype a recent technological breakthrough: an optical nosex000D
on chip made of a matrix of optical gas sensing pixels. Optical noses integrated on chip present numerousx000D
advantages over electronic noses such as low power requirements, robustness, and immunity to electromagneticx000D
fields, remote sensing and lower price. Miniaturized on-chip sensor, designed to detect air-borne compounds,x000D
are essential for inexpensive monitoring systems that are portable and deployable on a large scale [1-2]. Givenx000D
our experience with on-chip optical devices and more specifically optical gas sensors we have developed in thex000D
past, Odotech has required our help to investigate if on-chip optical sensors could answer its needs whilex000D
retaining satisfactory sensitivity. Within the frame of a recently completed NSERC Engage project withx000D
Odotech, we tailored the optical sensing device we developed previously, which is based on a reversiblex000D
absorption of a gas with a dedicated polymer matrix. The sensor is integrated on chip and is therefore small,x000D
compact, and can be distributed in a network enabling low power consumption. We demonstrated that it canx000D
monitor several volatile organic compounds (VOCs), such as alcohols, aldehydes, ketones, carboxylic acids,x000D
amines and aromatics, that it operates in a reversible fashion, under different environmental conditionsx000D
(temperature and humidity), and that it detects concentrations in the order of parts per million (ppm). Thex000D
objective of this NSERC INNOV proposal is to develop a fully functional prototype of an optical nosex000D
comprising a 6-sensor matrix with integrated light source and detector.
