Non-invasive EKG and insulin monitoring technologies offer real-time health tracking without needle pricks or implants, revolutionizing patient comfort and preventive care. Wearable devices equipped with optical sensors, sweat analyzers, and microwave or electromagnetic-based biosensors allow continuous measurement of cardiac and glucose parameters. AI algorithms enhance accuracy and predict abnormal patterns for early intervention. These technologies support diabetic care, cardiac rehabilitation, and remote health monitoring, aligning with trends in digital health, personalized medicine, and decentralized diagnostics.
