Scientists find: Human skin acts as antenna
By Guy Griml

Scientists at the Hebrew University applied physics department have discovered that human skin acts as a tiny antenna operating on "sub-terahertz" frequency. Using this discovery, researchers could collect data on blood pressure and pulse rate, for instance. The discovery is based on the finding that sweat ducts have a coiled structure similar to coil antennas in wireless communication systems.

The researchers note in a paper that the findings could serve as the basis for long-distance sensing technology that reads various physiological and emotional parameters, and could lead to the development of a variety of medical and security applications.

But the researchers emphasized that the study is still in its early stages. The discovery was announced by professors Yuri Feldman and Aharon Agranat, Dr. Paul Ben Ishay and research associates Dr. Alexander Pozansko and Dr. Andreas Kardof.
