Microwaves could replace electrodes for monitoring vital signs

In the not-so-distant future, patients having their heart rate or other vital signs monitored may not have to be wired up with electrodes. Scientists Atsushi Mase and Daisuke Nagae, at Kyushu University in Japan, have developed a method of remotely measuring such data using microwaves. This means that people would be free to move around as they were being monitored, or in some applications, would not even know that it was happening.
