A non-invasive blood glucose meter (professional name: non-invasive glucose monitor) is a medical device that measures blood glucose levels without piercing the skin. The device is designed to conveniently and painlessly measure blood glucose levels in both diabetic patients and healthy individuals. Unlike traditional finger-stick methods or implantable continuous glucose monitors (CGMs), non-invasive blood glucose meters use optical, electromagnetic, or electrochemical technology to analyze glucose levels in body fluids (such as sweat and tears) or skin tissue, helping to reduce pain and infection risks.
