Imagine if you could eliminate the tangle of wires that snake across a hospital patient's body so machines can monitor his or her vital signs. Sounds like a great idea. But wirelessly transmitting data from the patient to the machines cluttering hospital rooms creates the risk of electromagnetic interference. So one group of researchers in South Korea is proposing that some machines use Li-Fi instead.

The team used visible light communications, also known as Li-Fi, to transmit readings from an electroencephalograph (EEG) over a distance of about 50 centimeters. "It's a very much friendlier means of transmitting biomedical signals in a hospital," says Yeon Ho Chung, an engineer at Pukyong National University in Busan. The group described their work in the IEEE Sensors Journal.

Li-Fi would benefit places that experience a lot of interference from crowded wifi nodes as well, as long as there are no side effects.

    That works for me as long as they don't eliminate the sticky contacts for the cables. It would ruin my "I am Scaramanga" line.

    At last! Someone else who has the same compulsion to say that!
