Explosive vapor detection using microcantilever sensors

This chapter describes explosive vapor detection by using microcantilever sensors. Explosive-based violence is a renowned threat to a civilized and free society. Cost-reducing explosive sensors are necessary for fighting attacks and also, these sensors are necessary for tracing quantities of explosives. The sensors should also have the ability of mass consumption because of the terrorist threats concerning explosives. UMS can be formed with the use of accessible microfabrication methods. UMS are generally micromachined from silicon wafers using conventional techniques. These sensors can be operated in active mode, UMS-based sensing are able to satisfy many necessities for a superlative explosive sensor. UMS have enormously huge sensitivity and are well-matched with array agreement for coincident detection of numerous analytes. They have low power consumption and diminutive size. UMS technology has been confirmed in responsive detection of chemical, physical and also biological analytes. The Resonance frequency form is truly related to the procedure of another gravimetric sensor such as quartz crystal microbalance (QCM) as well as surface acoustic Wave (SAW) transducers.
