"The conventional treatment protocol causes a lot of stress for diabetics since it requires painful and repetitive blood-withdrawal and insulin shots," Lee said in a press release. "A recent alternative approach, sweat-based monitoring offers a painless blood glucose monitoring method, enabling more convenient control of blood glucose levels."

The research group presented an easy-to-use and multistage module to ensure an accurate glucose monitoring, the IBS said. To speed up the sweat collection, the researchers developed the system to work with only a small amount of sweat.

"This accurate glucose analysis would prescribe a multi-step and precisely controlled dosage of drugs to diabetes patients," the IBS said.

The findings were published in the journal "Science Advances." (Yonhap)
