Researchers at the University of California are developing a novel wireless communication technique, dubbed magnetic field human body communication. It delivers magnetic energy between wearable devices by transmitting it through the human body. "In the future, people are going to be wearing more electronics, such as smart watches, fitness trackers and health monitors," said study leader and UC San Diego professor of electrical and computer engineering Patrick Mercier. "All of these devices will need to communicate information with each other. Currently, these devices transmit information using Bluetooth radios, which use a lot of power to communicate. We're trying to find new ways to communicate information around the human body that use much less power." More
