We asked the experts if biological sex affects heart rate sensor accuracy
We already know thatskin tone can affect the accuracy of a heart rate sensoron a smartwatch or fitness band, but what other factors can influence the results you get? For example, does biological sex make a difference? To find out if heart rate sensor accuracy changed, we asked the experts. Here’s what they told us. Why ask the question? Why ask the question in the first place? Most heart rate sensors on wearables are photoplethysmography (PPG) sensors, which use light to detect the rate of blood flow, and it shines through skin and tissue to get that data....
