How Do Smartwatches And Fitness Trackers Measure Heart Rate?
It was around 6th April, in the midst of the covid-19 lockdown, my brother got an apple smartwatch as a gift. He bought it for me and asked he will show magic.
I wore the smartwatch and the magic started. I was able to see my heart rate, steps I was walking, Music, and all the other good things.
Next minute I was on google searching how the smartwatch actually works?
If you also wonder how smartwatches measures heart rate, Here is the answer-
Have you ever seen green light below the smartwatch? The secret lies there only.
Smartwatches track heart rate using the green LED’s which send rays into your wrist and scan the rate of blood flow. Now you might have doubt, are these reading correct? The reading is nearly precise as the vein in the wrist may have different pressure than the vein near the heart.
Moreover, a smartwatch gives you a warning if it detects any unusual activity in the heart.
How Do Smartwatches And Fitness Trackers Measure Steps?
Heartrate is fine as the fitness tracker is worn on the wrist and can measure. But we don’t wear a smartwatch on our legs. So, how does smartwatch and fitness trackers measure steps?
Smartwatches and fitness trackers measure steps by the sensors which monitor every movement of a body with 3 axis accelerometer. And the smartwatch/fitness tracker monitor movements like walking, running, and in fact, if you are standing still.
How Do Smartwatches And Fitness Trackers Measure Sleep?
Most smartwatches come equipped with a “sleep mode”. This mode requires to be enabled to track the different sleep patterns i.e. deep sleep, light sleep, and REM sleep.
I know you might be thinking that what exactly these sleep patterns are? Believe me, guys, these patterns are very simple to understand.
When we go to the bed and just start to sleep, our body movement reduces, and the heart rate goes down. This sleeping phase is called Light sleep. In the deep sleep phase, our heart rate goes down significantly and body movement reduces almost zero.
And, in the REM sleep phase, our eyeball moves left to right at a rapid pace. This is the time when we actually get dreams. This is why it is called REM (Rapid Eye Movement) sleep which goes 20-40 min for an average human being.
But here the question remains, how actually a smartwatch/fitness tracker measure sleep patterns?
To measure sleep patterns, the sleep mode of a smartwatch leverages the heart rate sensor and accelerometer sensor to track the speed and direction of motion and heart rate of a human. They take the body movement and heart rate as a consideration based on the different sleep phases, and measures sleep.
