Single sensor electronic nose, trainable for different industrial applications

Client: K. N. Toosi University of Technology

Start Date: 2005-2017

Director project: Prof. Faramarz Hossein-Babaei

Project type: Laboratory implementation

Project collaborator: Dr. Seyed Mohsen Hosseini-Golgoo, Dr. Amir Amini

Summary of project:

Sensor array-based electronic noses suffer from multi-dimensional drift and require cumbersome callibrations frequently. In this project, a virtual array-based electronic nose is developed which can repeatably operate over long term. The device utilizes only one chemiresistive gas sensor which is stimulated with thermal shocks of varying profiles and magnitudes. The temporal responses of the sensor, recorded as voltage variations, are processed for obtaining information regarding the nature of the gaseous analyte. The system is used for the comparison and recognition of analyte classes after appropriate training. The device can discriminate among both simple and complex odors in only 4 s.
