Scientists claim that when you’re in fear or nervous, you shall be sweating a lot and they’ve made a device that is able to detect your fear from your smelly sweat.
The scent signal contained in the sweat will tell if a person is scared. The scientists have carried out study on the underarm secretions of 20 terrified novice skydivers, and they have proven that the smell of the sweat reflected their fears.
The fear detector would be best used to identify terrorists or those who have committed wrongdoing at checkpoints. Currently, the researchers have got only a prototype of this device. They still have some obstacles to overcome such as it’ll not give reliable detection for those who wear perfumes or who with weird body odors.
