For Future Wearable Devices, the Network Could Be You

angry tapir writes: Researchers at the University of California, San Diego, have found a way for wearable devices to communicate through a person's body instead of the air around it. Their work could lead to devices that last longer on smaller batteries and don't give away secrets as easily as today's systems do. From the Computerworld story: "A team led by Professor Patrick Mercier of the university's Department of Electrical and Computer Engineering has discovered a way to use the body itself as the medium for data transmission. It uses magnetic fields and shows path loss that's 10 million times lower than what happens with Bluetooth. This could make the magnetic networks much more efficient, so devices don't have to work as hard to communicate and can have smaller batteries -- or get longer useful lives with the same size batteries. The team hasn't actually tested the system's energy use yet. They envision the technology being used for networks of health sensors that monitor many parts of the body."

    Personal area network card

    A personal area network card utilizes a computer network for communication with other devices, in proximity to an individual's body.

    In the 2000s, PAN cards were used in the facilities of both Shadow Moses and the Big Shell, also serving as ID cards for base personnel. The card system transferred data by passing minute electric currents using the salt in the user's body as a transmission medium. PAN cards could be carried anywhere on one's person and unlock doors automatically. During the Big Shell Incident, Otacon was supposed to get PAN cards for the SEAL Team 10's Bravo Team, while undercover as a chief architect of the facility's security systems, but failed to do so.

      Some people claim to interfere with electromagnetics. I had a friend who swore she could not use a watch as they would stop functioning after being on her body for a small amount of time. She also kept a cheap flip phone and said she went through those about once a year. I don't know and never got her near test equipment to see.

      Not sure if this is related but a friend of mine used to constantly set off metal detectors and store alarms when he was a teenager, even though he wouldn't be carrying any metal objects or security tags. We used to find it funny, but it was annoying for him. The effect eventually disappeared after a few years, and we never got to the bottom of it.

    So it changes WiFi frequency from a harmful band into a harmless one...using quantum mechanics and holograms. Dipshit! Do you even Science?
