Enhancing the accuracy of wearables

[skb]

Many researchers have proposed noninvasive methods to monitor BGLs using widely available wearable devices, such as smartwatches. For example, by placing the LEDs and photodetectors present in certain smartwatches against the skin, oxyhemoglobin and hemoglobin pulse signals can be measured to calculate a metabolic index, from which BGLs can be estimated. However, given the small size and limited power of smartwatches and similar wearables, the data quality of the measured signals tends to be quite low.

I know that this is something Apple is working on but it is probably not going to happen soon. People are asking for it but it needs to be accurate to be useful.
