Gear S4 may come with a blood pressure monitor, Samsung patent reveals
Apple has made a big fuss out of the health-tracking options that its Watch wearable reveals, and with a good reason. The healthcare sector is a $3 trillion industry, so even a tiny fraction of it holds huge revenue potential. The Watch is even engaged in one of the largest heart studies, thanks to its position as the world's most popular wearable, and Apple has big plans to outfit it with more functions in the future.

What's been eluding most smartwatch and fitness tracker makers, however, is the ability to measure, store and monitor a vital that is arguably even more important than your heart rate - your blood pressure. Everyone does heart rates, and Samsung has had a pulse meter embedded in its phones since the days of the Galaxy S5, but nobody can yet do blood pressure, unless attached to a 3rd party cuff, as you can see in our roundup. Well, Samsung's latest patent might be about to change that.

The smartwatch depicted there is even smaller than the Omron HeartGuide, the only fitness tracker/watch so far that would take blood pressure measurements on its own, and comes in a much smaller footprint than the usual monitors, yet it still has to be inflated. The one that Samsung has patented relies on a completely different principle - still with light beams, like the heart rate sensors, and measuring their scattered patterns, but returning your actual blood pressure readings via different decoding algorithms. 

This would be the best of both worlds - using existing technology and sensors, but rolling out two functions instead of one in the Gear S4, or whatever generation Samsung readies this patent for. Needless to say, if this ever sees the light of day, it will be a complete healthcare breakthrough, as it might be able to scan your blood pressure on a continuous basis, and alert you or your doctor as needed, when things get out of whack.

I hope they return to square watch with curve screen like Samsung gear S the original version and make it with front camera for selfie and video calls ! It will be fantastic

This article is about health related features, specifically blood pressure monitoring.

I hope they don't. I owned that watch. Not only was it crappy in function, it was ugly as sin.

That would be great! Most people don't know their average blood pressure, while a high blood pressure is a major risk factor for cardiovascular diseases. This could actually be used for prevention. Way more useful than heart rate only which doesn't tell you that much.

I bought a pretty reliable one, but one on my wrist would rock.

It's an impressive feature to add to Samsung's already quite extensive health surveying features, which isn't really matched by many, if any. A good example is Samsung phones, which can already measure your heart rate, stress levels and your blood oxygen level. I actually was at a hospital lately, where i A/B tested the blod oxygen level reading from the Samsung Galaxy S6 edge compared to the proffesional equipment, and the S6 edge was within 1% of the proffesional one during my tests. I didn't think it was really that accurate, but clearly it's quite good.

That alone would get me to buy an S4. Man, would that be awesome on top of all the crazy stuff Samsung smart watches already do.

Well maybe I need to hold off on buying a Gear S3 for my new Note 8 then....although if it uses the existing sensor maybe Samsung will enable it on past watches down the road(or some enterprising XDA user will)

If that's true, will definitely order one
