Machine Olfaction Device (MOD) Chambers with Two Sensors

Najib Altawell

The Electronic Nose (or eNose) presently possesses a number of challenges, such as short life-time of the sensors; sensitivity towards moisture; narrow selectivity; relatively expensive; mostly used as a laboratory tool and in some cases results can be difficult to reproduce due to the presence of multiple sensors.

The present available devices either lack mobility or are not designed for a long term use. Most of these devices use arrays of sensors, i.e. eNoses, rather than two sensors. Also, the design of the chamber in most present devices can add problems, such as replacement of the sensor, long term functionality and other related issues.

This paper is aimed at developing a novel and improved machine olfaction device (MOD) with on-board data processing capability for monitoring applications. Such a system will be able to use two sensors rather than an array of sensors, as is the case with the present eNose devices. The aim is for a real time MOD which can be used inside and outside the laboratory and for domestic and commercial purposes as well. This new approach can be achieved within the design provided in this paper.
