Many people with diabetes measure their blood sugar levels with finger-stick checks a few times a day. To remove such pains and inconvenience, we design a new kind of wearable sweat test paper, also called the skin-surface-glucose test paper which can be attached to most body surfaces with the edges of only 1mm thickness. The circles in the center of the paper, symbolizing the logo of World Diabetes Day, contain chemical reagent which can react with only 0.1ml sweat to visually display the blood glucose level by color changes.
