Pain-free blood sugar testing for diabetics
Hong Kong scientists have invented a device to help diabetics measure their blood sugar painlessly for the first time – without pricking their fingers.
The size of a mobile phone, the instrument emits a weaker form of infrared, or near-infrared, which penetrates the skin on the finger and homes in on the bloodstream.
Out of the many components in the blood, the beam is able to identify bits of glucose through the frequency, or wavelengths, they transmit and the amount of blood sugar present would be displayed on the instrument in 10 seconds.
