Medical wearable sensors are small electronic devices designed to monitor health-related data continuously while being worn on the body. These devices are typically embedded in accessories such as smartwatches, patches, clothing, or bands. They exist to provide real-time tracking of vital signs like heart rate, physical activity, sleep patterns, and even blood oxygen levels.
The development of these sensors is closely linked to advancements in digital health technology and the growing need for preventive healthcare. By collecting data outside traditional clinical settings, wearable sensors help bridge the gap between patients and healthcare providers.
