Chementator: Smelling false alarms

By Chemical Engineering |

An electronic nose capable of distinguishing between cigarette smoke and smoke from an office or factory fire has been developed by a consortium of nine European companies and research institutions, with funding from the EU’s IST (Information Society Technologies) program. A prototype of the Intelligent Modular, multi-Sensor (IMOS) and networked fire-detection system has been constructed, and the researchers hope to have a commercially viable product ready by October. After identifying the chemicals associated with smoke from burning sources, such as wood, cotton, paper, plastic (polyurethane) foam and cigarettes, the researchers developed dedicated sensors, based on conductive polymers, to recognize these materials. The device was developed to reduce the number of false alarms. Today 90% of regular fire alarms are false, says Florence Daniault, the project coordinator at Wagner Alarm- und Sicherungssysteme GmbH (Hannover, Germany; edlinks.chemengonline.com/5825-548).   Click here for a full pdf version of the Chementator Section
