Swedish scientists say they have developed a very small system of skin patches containing a micro-needle in the small one to monitor blood glucose levels in blood for diabetics. They successfully tested their first models on humans and were preparing for clinical trials.
The patch keeps the glucose level constant. It will therefore replace current devices that are uncomfortable because they require either a 7-millimeter long needle in the skin or penetration into adipose tissue, said researchers at KTH Royal Institute of Technology in Stockholm. Not the best places to measure sugar.
The patch containing a needle was 50 times smaller than the previous needles, said the researchers. The use of sensors for enzymes helps to analyze glucose over long periods. The patch starts working 10 minutes after placing it on the arm skin.
