Improvised Explosive Device (IED) Detection

In a biological system, smell is detected by specialized receptor cells of olfactory epithelium called olfactory receptor neurons (ORN). Specialized odor binding proteins (OBP) transports odorants across the mucus layer to the receptors. The role of receptor is taken by a sensor that can convert the detected chemical into an appropriate electrical signal. A chemical sensitive material layer over the sensor acts as the odor binding protein. This layer can be made sensitive to particular chemicals of interests thereby allowing the system to detect the presence of that particular chemical. The target chemicals are of wide variety as an IED can be made using any one or a combination of these chemicals. High explosives can contain any of potassium nitrate, ammonium nitrate, potassium chlorate, red phosphorus, perchlorates, nitroglycerin, TNT, Nitrocellulose, RDX and PETN. A sensor array, containing multiple sensors, is used to distinguish different chemicals. Our Improvised Explosive Detection (IED) system would has a sensor placed in a remote controlled vehicle, able to detect the presence of explosive chemicals.
