Sweat ducts may act as giveaway 'antennas'
Our skin may contain millions of tiny "antennas" in the form of microscopic sweat ducts, say researchers in Israel. In experiments, they found evidence that signals produced by bouncing electromagnetic waves off the tiny tubes might reveal a person's physical and emotional state from a distance.
The research might eventually result in lie detectors that require no physical contact with the subject.
In other words: "Voight-Kampff 2.0."
