E-Nose (E)

The human nose functions as a tiny machine to gauge and analyze the nature and extent of the smell emanating from a source. In some animals, the role is extended to determine social behaviour and even reproduction! Scientists have been trying to replicate our senses. The major challenge lies in converting bio-signals into electrical signals implying the merging of biology and electronics. So is it possible to create an electronic sensor that can smell like our noses? The answer is E-Nose. Watch this programme to know what is E-Nose, where is it useful and how it functions.
