Sweat ducts in human skin act like an array of tiny antennas that pick up radiation at specific frequencies. This finding might be used in medical and security technologies to assess a person's mental state from a distance. The antenna behaviour is all down to the ducts' curious shape. Filled with electrically conductive sweat, these channels act rather like coils of wire that absorb radiation across the millimetre and sub-millimetre wavelength band. The researchers found that the reflection signals are proportional to blood pressure and pulse rate and are known indicators of physiological stress leading to sweating.
