Human magnetic field offers communication hope
 

Researchers at the University of California San Diego believe they have hit on a method using the human body to allow communication between different wearable devices.

The electrical engineers showed off a wireless communication method that sends magnetic signals through the body which offers a better method of communicating than, for example, Bluetooth.

A demonstration at a conference in Italy showed a “proof of concept” method that they believe could be developed into an ultra low power wireless system to transmit data.

Patrick Mercier, a professor at the university, said: “In the future, people are going to be wearing more electronics, such as smart watches, fitness trackers and health monitors. Currently these devices transmit information using Bluetooth radios, which use a lot of power to communicate.”

He said that Bluetooth uses electromagnetic radiation to transmit data but radio signals are partly blocked by the body and so need extra power.
