Engineers at UC San Diego have created a device that will allow ultra-low-power wireless connectivity with monitors and wearables using the human body as the communication path Be it on the inside or the outside, the human body is becoming host to an ever-increasing array of electronic devices that need to wirelessly communicate with each other. Now engineers working at the University of California, San Diego have come up with a different type of wireless communication that sends ultra low-power magnetic fields through the human body.
