---- Even Immanuel Kant singled out smell as the
sense that was “most dispensable” because “the
pleasure coming from the sense of smell cannot be
other than temporary.” However, scents can be a
significant source of information and over
evolutionary time, the human nose has developed to
identify numerous scents vital to survival. The
importance of smell has recently been recognized,
and over the past few decades, researchers and
engineers have created increasingly sophisticated
electronic systems to detect and identify numerous
odours to augment the biological restrictions of the
human nose.
