Smart Healthcare Systems Using Wearable Devices: A Review

Abstract

Wearable technology is changing the way healthcare is provided because it promotes real-time and constant monitoring of physiological parameters beyond the hospital. Remote patient monitoring, chronic disease management, preventive care and personalized wellness Smart healthcare systems based on wearables and Internet of Things (IoT) connectivity, cloud analytics and artificial intelligence (AI), are increasingly popular. This review analyzes the existing environment of wearable device-based smart healthcare systems, presents the device architecture, data collection and analytics algorithms, clinical environment, advantages and disadvantages. The main opportunities are better patient outcomes, lower healthcare expenses and increased patient engagement whereas the main challenges remain associated with the sensor accuracy, data privacy, interoperability, power independence and clinical validation. The recent research is condensed to find out the next trends, including federated learning of wearable data, energy-independent sensors and wearable assimilation into the larger medical ecosystems. The results are expected to inform researchers, clinicians and system designers to design and implement wearable based smart healthcare solutions.
