X-niff: Microcantilever Based Electronic-nose Platform For Airborne Chemical Vapor Sensing Applications.
Project Description :

The present invention is the electronic nose system for explosive sensing using polymer piezoresistive microcantilever sensors. the electronic nose contain sensor array, sampling and transport stage, front end analog instrumentation and pc/tablet/laptop for data analysis and pattern recognition. sensor array with range of different coatings increased selectivity of the system for explosive detection. the engineered system can detect explosive material in the ambient conditions in both swipe based as well as vapor collection technique and can differentiate with non-explosives. highly sensitive stacked based multi-channel analog instrumentation readout circuit for interfacing sensors is used. collected responses from the sensor is given to tablet or pc for data processing and pattern recognition. we also propose a novel hybrid pattern recognition algorithm for a better accuracy in explosive sensing and reduced rate of false positives. this invention relates to the multichannel electronic nose system for trace explosive sensing. it relates to a trace detection of explosive material like tnt, petn, rdx and other derivatives of explosive in presence of external interferents using microcantilever based sensing platform. it also relate to use of pattern recognition algorithms to selectively indentify explosives from non-explosive material.
