Introduction

Rapid advancement in digital technologies has significantly transformed modern healthcare systems, creating new opportunities for intelligent monitoring and early diagnosis of diseases [1]. Traditional healthcare frameworks depend largely on periodic medical examinations conducted in hospitals or diagnostic laboratories. Such episodic assessments provide only limited insight into the dynamic physiological changes occurring in the human body during daily activities [2]. Continuous monitoring of health conditions therefore represents a critical requirement for improving preventive healthcare and reducing disease-related complications. Wearable Internet of Things (IoT) devices have emerged as an important technological solution that enables real-time monitoring of physiological signals outside clinical environments [3]. Integration of miniature biosensors, embedded processors, and wireless communication technologies has enabled the development of compact wearable devices capable of collecting vital health information continuously. These devices capture physiological parameters such as heart rate, body temperature, blood oxygen saturation, respiration patterns, physical activity levels, and sleep behavior. Collected data are transmitted through connected networks to digital healthcare platforms for storage and analysis [4]. Continuous acquisition of physiological signals provides a comprehensive representation of an individual’s health condition over extended periods. Such longitudinal health data enable early recognition of abnormal physiological patterns that may indicate the onset of medical conditions [5]. Growing interest in preventive healthcare and remote patient monitoring has therefore accelerated research and development in wearable IoT technologies designed for continuous health monitoring and early disease detection.

Wearable IoT technologies combine sensing, communication, and data analytics capabilities within compact electronic systems designed to be worn on the human body [6]. Smartwatches, fitness bands, biosensor patches, and smart textiles represent common forms of wearable devices currently utilized for monitoring physiological parameters. These devices integrate multiple sensing modules capable of detecting biological signals associated with cardiovascular activity, respiratory function, metabolic behavior, and body movement [7]. Sensors embedded within wearable devices convert biological signals into electrical signals that undergo digital processing through embedded microcontrollers. Wireless communication modules integrated within wearable platforms enable transmission of processed physiological data to mobile devices, gateway systems, or cloud-based healthcare platforms [8]. Continuous connectivity between wearable devices and digital healthcare infrastructure supports uninterrupted monitoring of patient health conditions. Remote access to physiological data allows healthcare professionals to observe patient health status outside hospital environments and respond promptly to abnormal health events [9]. Integration of wearable technologies within telemedicine platforms has strengthened accessibility to healthcare services for individuals located in remote or underserved regions. Digital health ecosystems built upon wearable IoT frameworks therefore support proactive healthcare management and reduce dependence on traditional hospital-centered medical practices [10].
