Flexible Patch Tracks Blood Sugar During Exercise

A new wearable patch would let diabetics track their glucose levels during exercise. While exercise is important in maintaining good health, people with diabetes must watch their blood sugar levels carefully to make sure they stay in the safe range. To help make this easier, a paper patch was developed and is able to measure glucose in sweat. The flexible patch can monitor blood sugar levels using capillary action, without an external power source.
