Scientists have developed a sensor that monitors blood sugar levels by analyzing sweaty skin.
But you don't need to go to the gym to sweat a wet T-shirt, you only need 0.01 ml of sweat to carry out this test.
The research team from South Korea showed that the sensor is very accurate and that it can ultimately help diabetics.
In an additional test performed on mice, the sensor was connected to a small needle that automatically injected the diabetes drug.
The Seoul National University research team is trying to overcome the pain of patients with diabetes.
Type 1 diabetes is caused by the immune system attacking parts of the body that control blood sugar levels.
Type 2 diabetes is usually caused by the ability of the unhealthy lifestyle to impair the body's ability to control blood sugar levels.
From a medical point of view, both types of diabetics need to control blood sugar levels to prevent physical damage or even death.
This is the usual method of monitoring blood glucose levels in people with diabetes:
This may be the way to the future:
The sensor is very flexible so it can move with the sticky skin.
However, scientists need to overcome a range of challenges to make them work.
The sugar in the sweat is much less than in the blood, so it is difficult to monitor, and other chemicals such as lactic acid contained in the sweat can also destroy the blood sugar test results.
Therefore, the patch has three sensors for tracking blood sugar levels, four sensors for detecting the acidity of sweat, and a humidity sensor for analyzing the amount of sweat.
It is wrapped in a porous layer that can be soaked in sweat and cleaned.
All of this information is passed to a portable computer for analysis to calculate blood glucose levels.
The test "People sit down before and after eating" published in the journal Science Progress shows that the test results of sweat patches are "highly consistent" with traditional kits.
However, in the next phase, the researchers' research will turn to diabetic mice.
They used a blood glucose monitor to control a row of microneedles to inject mice with the diabetes drug metformin.
The researchers concluded: "The system currently provides important new advances in painless, stress-free diabetes care."
However, there is still a big leap in the laboratory to prove that something can sense blood sugar levels and turn them into people who can give life to their control.
Therefore, the next step for the researchers is to test how the patch works long-term.
