For future wearables, you are the network
People who wear networked gadgets all over their bodies may someday become networks themselves.
Researchers at the University of California, San Diego, have found a way for wearables 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.
The proliferation of smartphones, smart watches, health monitoring devices and other gear carried close to the body has led to so-called personal area networks that link the gadgets together and provide a path to the Internet through one that has a Wi-Fi or cell radio. Today, those PANs use short-range over-the-air systems like Bluetooth.
