Anti-terrorist device will be able to ‘smell’ fear
Monday, 2 November 2009
A device that smells human fear is being developed by British scientists and could soon be sniffing out anxious terrorists.
The technology relies on recognising a pheromone — or scent signal — produced in sweat when a person is scared.
Researchers hope the “fear detector” will make it possible to identify individuals at check points who are up to no good.
Terrorists with murder in mind, drug smugglers, or criminals on the run are likely to be very fearful of being discovered.
However calm they might appear on the surface, their bodies could give them away.
Although the research is at an early stage, the aim is to develop a prototype device in the next two to three years.
Evidence that the smell of fear is real was uncovered by US scientists last year who studied the underarm secretions of 20 terrified novice skydivers. The researchers found that people appear to respond unconsciously to the sweat smell of a frightened person.
Scientists at City University London now hope to develop security sensor systems that can detect the human fear pheromone.
Team leader Professor Tong Tun told The Engineer magazine: “The challenge lies in the characterisation and identification of the specific chemical that gives away the signature of human fear, especially the fear in relation to criminal acts.”
The project will look at potential obstacles to reliable detection such as the effects of perfume.

Detecting fear in an airport should not be that difficult. Many people have an irrational/rational (depending on how much they know) fear of flying. I expect that this machine will be very busy indeed, as will be the trade in latex gloves.
