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

该项目旨在将最近的一项技术突破整合到一个功能原型中：由光学气体传感像素矩阵制成的光学鼻子芯片。与电子鼻相比，集成在芯片上的光学鼻具有许多优点，例如低功耗要求，鲁棒性，抗电磁场，遥感和更低的价格。小型化的片上传感器，设计用于检测空气中的化合物，对于便携式和可大规模部署的廉价监测系统至关重要[1-2]。鉴于我们过去开发的片上光学器件和更具体的光学气体传感器的经验，Odotech要求我们帮助调查片上光学传感器是否可以满足其需求，同时保持令人满意的灵敏度。在最近完成的与thodotech合作的NSERC Engage项目框架内，我们定制了之前开发的光学传感设备，该设备基于专用聚合物基质对气体的可逆吸收。该传感器集成在芯片上，因此体积小，结构紧凑，可以分布在网络中，从而实现低功耗。我们证明了它可以监测几种挥发性有机化合物（VOCs），如醇、醛、酮、羧酸、胺和芳烃，它在不同的环境条件下（温度和湿度）以可逆的方式工作，并且它可以检测百万分之一（ppm）的浓度。这个NSERC INNOV提案的目标是开发一个全功能的光学鼻子原型，包括一个集成光源和探测器的6传感器矩阵。
