Like our proboscises, e-noses are only as good as their sensors, and all of them operate on principles remarkably similar to those of a real nose. Humans detect odors with up to 650 types of receptors found on cells high up in the nasal passages, somewhere between our eyebrows. How the nose works is still something of a mystery, but it is believed that each receptor responds to a subtle characteristic of a molecule that carries odor--its peculiar shape, say, or degree of oiliness--rather than to the molecule itself. Working together, the receptors can generate unique "smell...
