Medical Tricorder

Star Trek overalps with reality again in the form of a functional medical tricorder:

It is a tiny, round and rigorously white device -- even though a black version is in the plans -- and it works by placing it on one's forehead.

Through its sensor, and in a matter of seconds, the Scanadu measures heart rate, temperature, blood pressure, oxygen level and provides a complete ECG reading.

Not a very interesting form factor. You certainly won't be impressing any ignorant native species with it, but that's because it's basically just a box full of sensors which ties into your smartphone.

Still waiting impatiently for phasers, by the way. My list of people who need disintegrating grows daily.
