Blood glucose sensor to replace the drop of blood
A non-invasive process that would change the lives of diabetics, who for the moment have no other way to measure their blood sugar than to prick their finger in order to collect a droplet of blood, which is placed each time on a special disposable strip, which is then inserted into a glucometer.
