Star Trek tech No. 7: Tricorders
From the Fit Bit to Nike Fuel, devices that can wirelessly monitor our health are proliferating faster than you can say, “Dammit Jim, I'm a doctor, not an engineer.” How close are we to a working Tricorder? Qualcomm is offering a $10 million X Prize to the first team to build a portable diagnostic device that can measure vital signs and detect at least 15 diseases. Meanwhile, impatient Trekkers have already built boxy Linux-powered science Tricorders that can detect atmospheric, electromagnetic, and spatial properties. Fascinating, captain.
