For Future Wearable Devices, the Network Could Be You 23
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 networks using you as the cable. 1996 pretty sure this wasn't even the first.

But that's the way it is with patents; they're like survey questions, it's all in how they're phrased. Maybe this time someone will actually produce something with the idea?

You go bonkers/wrong if you wear a watch? Therapy, I'd say.

Miss, I have valuable information I need to communicate to you directly. (Yes it's been done to death in spy movies.)

Through-the-body communication chips have been around a while; you can click-n-buy them right on Digikey.
