Dr. McCoy’s tricoder isn't looking too futuristic these days. Not only are real life versions of the Star Trek device under development,
but some new medical devices are making it look a bit old fashioned.
Take, for example, the ViSi Mobile vital signs monitor built by Sotera
Wireless of San Diego, California. This wearable sensor pack uses Wi-Fi
technology and is claimed to allow doctors using a tablet or smartphone
to remotely monitor patient vital signs with the accuracy of an
intensive care unit.
