Up to now the problem of detection of explosives especially the location of explosives whether at large areas e. Other electronic sniffers use fluorescent polymers to detect odors or explosives but are less indicative of the presence of explosive material because only a single fluorescent molecule is quenched by the explosive. Offered vapor detector is Capable of detecting at least 10-13gcm3 TNT at 20degC 80RH non condensing.

Additionally sensing elements which have the potential to be applied for the electronic dog nose are described. Further the ultra-high sensitivity and low cost of polymer nano-composite microcantilever can lead to the development of a rugged portable handheld device for rapid and sensitive detection of explosive vapors. As shown in Fig.

Methods of detection of Improvised Explosives IE. The proposed device is compact low power and low cost. We present the design construction and measurements of the electronic response of a 16 channel electronic nose based on 16 differ.

The fast detection of explosives from the vapor phase would be one way to enhance the protection of society against terrorist attacks. Good chemical selectivity of sensors for detecting vapour traces of targeted molecules is vital to reliable detection systems for explosives and other harmful materials.
