> World’s first watch with optical blood pressure monitor
> The BP-100 calculated blood pressure by analyzing changes in blood flow measured by an optical sensor and ECG signals. No wristwatch had ever incorporated a blood pressure monitor before. Simply touching a fingertip to the sensor produced a reading — and unlike conventional monitors, it was accurate without requiring constriction of the arm.
Wow. Why don't we have that yet in today's smartwatches?
