One of the view companies which seems to invests in the development of low-cost high-quality physiological sensors is Apple

But the Apple Ultra is everything else than low-cost. But is it high-quality? According to the data of Rob ter Horst, the Apple watch heart rate sensors have become more accurate. Is this because Apple wants to sell those to medical doctors?

That would be nice, because then Apple watches would also be of interest for physiologists. But only if someone other than Rob ter Horst checks their accuracy. And not with two Polar H10 chest straps, but with medical and research grade ECG devices. Someone as Dr. Milind Desai from Cleveland Clinic in Ohio.
