This is really interesting in that it doesn't use photoplethysmography (PPG) in the same way that the Galaxy Active 2 does(an optical sensor that measures bounced back light.) There's an inflatable cuff within the wristband. I'm assuming this will be a lot more expensive but calibration shouldn't be as much of an issue and it should be more accurate. |
