You know in Star Trek when Bones runs a mobile scanning device over some poor red-shirted schlub and comes back seconds later with a diagnosis? Well, that futuristic Star Trek tricorder is a step closer to reality today thanks to the Scanadu Scout, a handheld medical scanning device that works in conjunction with a smartphone to take all five vital signs in just 10 seconds. It will cost $150 and you can get it by the end of 2013.
Wired had the opportunity to play with a working prototype this week and it was, frankly, amazing. Hold the Scout to your temple and it registers pulse transit time (for blood pressure monitoring), heart rate, electrical heart activity, temperature, heart rate variability and blood oxygenation. The tracker then transmits that data to a smartphone app that clocks how those variables change over time. It's meant to give people greater control over their own health data and insights on how it might be changing.
For example, although 98.6 degrees Fahrenheit is the commonly accepted figure for human body temperature, that's an average and not standard across individuals. For some, 99 degrees might indicate a fever, while for others it's perfectly normal. By taking regular readings, and charting them automatically, the Scanadu Scout can help people understand what's normal for their own bodies.
The device, designed by Yves Behar, fits nicely in the palm of your hand, and is approximately the size of a makeup compact. But while the hardware is nice, what's truly exciting is the software back end.
The extensible software platform is meant to be opened up to input from other tracking and monitoring devices. Two immediate examples, both of which will be available in 2013, are the ScanaFlo and ScanaFlu. ScanaFlo is a small plastic wand with a row of urine test strips that can check for pregnancy complications, pre-eclampsia, gestational diabetes, kidney failure, and urinary tract infections. ScanaFlu has a small tray that you spit into and it checks for one of five respiratory diseases: Strep A, Influenza A, Influenza B, Adenovirus or RSV. While pricing hasn't been set for either, both are planned to cost less than a trip to the clinic.
Scanadu was the vision of heavyweight technologist Walter De Brouwer, who previously ran Emotiv and the European arm of One Laptop per Child, among many other things. De Brouwer began looking for a better way to understand personal medical data when one of his children was hospitalized for a year after falling from a window.
His solution to this was Scanadu, which is an entrant in the Qualcomm Tricorder X-Prize. De Brouwer describes it as the most difficult thing he has ever done, not only on the software side, but also on the back end, developing algorithms to crunch numbers and deliver insights. And still much has to be done -- for example, it will have to gain FDA clearance. But if it works, it could prove to be a powerful marriage of molecular diagnostic information with body sensors that could give patients an unprecedented control over their own health data.
