Non-invasive glucose monitoring remains one of the most sought-after goals in digital health. Among the leading candidates, wearable sweat sensors have attracted intense research interest because they promise painless, continuous metabolic tracking without needles or implanted devices. In 2025, prototype sweat-based glucose wearables are advancing rapidly—but significant technical barriers still prevent clinical-grade deployment. This article … Read more

Inside the Race for Non-Invasive Glucose Smartwatches

3D visualization of a futuristic smartwatch performing non-invasive glucose monitoring with optical sensors

For decades, people with diabetes have relied on invasive methods to monitor blood glucose—finger-prick tests or implanted continuous glucose monitors (CGMs). The promise of a truly non-invasive glucose smartwatch has long been considered the “holy grail” of wearable health technology. As we move through 2025, major technology companies, medical device manufacturers, and semiconductor firms are … Read more
