Wearable medical technologies are transforming healthcare services toward a preventive and personalized model. Clinically validated devices such as smartwatches, ECG belts, continuous glucose monitors, and smart garments enable real-time and remote monitoring of patients’ physiological data, including heart rhythm, blood pressure, and oxygen saturation. This continuous monitoring improves the management of chronic diseases, facilitates early diagnosis, and reduces hospital visits and healthcare costs. Advances in sensor technologies, wireless communication, and artificial intelligence–driven data analytics further enhance the capabilities of these devices. However, challenges related to data security, clinical validation, and regulatory standards must be overcome to achieve widespread adoption. Ultimately, wearable technologies constitute a cornerstone of a more proactive, efficient, and patient-centered healthcare system.
