Many smartwatches (even smartbands) can measure your heart rate, but very few can measure blood pressure. That’s because to measure blood pressure, you need a tight-fitting band that presses into your hand uncomfortably.
A patent shows that Samsung may have figured out a way to make the measurement with a light sensor similar to the heart rate sensors. The patent drawings show a watch, called Samsung Gear X (not to be confused with Gear IconX).
The design shown is similar to the original Gear watches and we’re pretty sure it’s just a placeholder (same for the name).
The way…
