Healthcare monitoring systems is an academic domain concerned with the systematic study, design, and deployment of technologies and methodologies for observing and analyzing health-related parameters. This concept encompasses the investigation of data acquisition techniques, signal processing, pattern recognition, communication infrastructure, and human-computer interaction within the context of continuous or periodic health surveillance. Its key characteristics include the integration of sensing devices, data analytics, and often remote access capabilities, aiming to provide timely insights into individual health status or population health trends. The significance of this research area lies in its potential to enhance preventative care, enable remote patient management, improve diagnostic accuracy, and support public health initiatives through data-driven insights.
