It’s called “Scanadu Scout” — after Xanadu, an ancient city of great splendor and scientific progress, made famous by English poet S. T. Coleridge — and the greatest thing about it is that it’s not a design concept, nor a million-dollar prototype, but an actual product. After a successful crowdfunding round via Indiegogo, the Scanadu has began shipping to backers at the end of January.

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.
