Self-Powered Paper Patch Measures Glucose

The most common methods for glucose self-testing involve monitoring glucose levels in blood. These conventional measurements are not suitable for preventing hypoglycemia during exercise. The underlying process relies on invasive and inconvenient blood sampling, which can cause skin irritation with perspiration containing electrolytes and proteins. In addition, blood testing requires that diabetics keep testing equipment such as lancets, alcohol, and a glucometer with them during exercise.
