SMART WEARABLE DEVICES IN MEDICINE: A REVIEW

Abstract

Smart wearable devices are the novelty of new medicine, wherein physiological parameters are continuously monitored in real time on-line, disease is continuously being monitored real time, and intervention in treatment is personalized. New sensors, wireless networking, artificial intelligence, and cloud computing technology are utilized by the technology to deliver preventive medicine, reduce hospitalization, and facilitate active patient involvement in healthcare. Wearables monitor vital parameters such as heart rate, oxygen in blood, glucose level, sleep, and physical activity and send safe information to health professionals to analyze in real time. Wearable technology expanded in 2021-2025 from healthcare and health and fitness to chronic disease prevention, elder care, rehabilitation, monitoring of mental illness, and public health crisis management, i.e., pandemic surveillance. While there is improvement underway, still there remains a gap to be bridged to attain data privacy, clinical validation, device compatibility, and limits of ethics and technology in the guise of sensor dependability, battery life, and not-interoperable protocols to avoid world-wide application. Reasearch is moving toward self-capability with AI for predictive medicine, blockchain and federated learning for secure data stewardship, and end-user-optimized best devices to take applications into everyday life. Future-gen innovation has in store wearables healthcare device paradigms, new applications and frontiers, and aligning future research agendas to keep adding value to everyday medicine.
