They do mention using microwaves, which do not get reflected. Microwaves are passing through your body as a type this.
I’m wearing a watch which measures my Blood Oxygen, works just like those in hospital. I’m currently at 99%. They work with two lights, red and infra red. Blood with enough oxygen absorbs more red light, blood with not enough absorbs more infrared. So they only work in areas where blood capillaries are close to the surface. They work on the effect of Oxygen on the red blood cells. Arterial blood is bright red, venous blood on its way back to the lungs and heart is dark red. Glucose doesn’t play any part in that colour change, so I’d be interested into what they are attempting to address.
