New device to make glucose monitoring 'painless' for diabetics
But the currently used continuous glucose monitoring systems (known as CGMS) are uncomfortable since they require a minimum 7mm needle inserted into the skin. Owing to their size, they take measurements in the fat tissue - not the most ideal location.
However, the new device, developed by researchers at KTH Royal Institute of Technology in Sweden, is 50 times smaller.
When applied to a human participant's forearm, the combination of the patch and an extremely miniaturized three-electrode enzymatic sensor was found capable of correctly and dynamically tracking blood glucose levels over time, with a delay of about 10 minutes.
"Our solution is painless to the user. We measure directly in the skin, and there are no nerve receptors that detect pain - just a fine mesh of very tiny blood vessels," Federico Ribe, a doctoral student at the institute, said.
This would offer an alternative to pricking one's fingers several times a day to take a blood test and the frequency of finger prick tests could be reduced with a glucose monitoring system, he noted.
The team has successfully tested the prototype of a microneedle patch on a human participant and the completion of a system for clinical tests is now underway.
