IIT professor creates 'E-dog' to sniff bombs
On its way to developing an ultra-sensitive low cost explosive detector, Indian Institute of Technology, Mumbai, will soon unveil an "e-nose" that will be several times stronger than a dog's olfactory power. This device, which is also informally called 'E-dog' by the developing team, will find out traces of RDX that existing machines fail to point out. It will be able to detect RDX from 1.5 feet. The e-nose, which uses a sensor coated with nano materials, is currently under development. V Ramgopal Rao, chair professor at the department of electrical engineering, IIT-Bombay and principal investigator at the institute's centre of excellence in nano-electronics, spoke about the device on the sidelines of the 8th Chandigarh Science Congress (CHASCON) at Panjab University on Wednesday. CHASCON is being organized by PU in collaboration with various leading educational and research institutions of the Tricity. The Electronic Nose, or E-dog, is the result of
