This evolution is setting the stage for a paradigm shift towards holistic health monitoring, fundamentally altering the landscape of healthcare. By leveraging continuous data collection, real-time analytics, and personalised feedback, modern wearables promise to enhance patient outcomes and healthcare efficiency.
Initial Forays and Limitations
The first generation of wearables primarily focused on fitness tracking. Pioneers like Fitbit, Jawbone, and Garmin developed devices that counted steps, monitored sleep, and estimated calorie burns. While useful for general health awareness, these early wearables were limited in scope and lacked the precision required for clinical applications.
To understand the scope of these devices, current market offerings include products like FitBit's Flex, which tracks steps, calories burned, sleep quality, and distance travelled. Amigo's fitness bracelet goes further by measuring specific exercises, repetitions, heart rate, and calories burned.
The Rise of Health-Specific Wearables
Recently, a plethora of wearables tailored explicitly for health monitoring has emerged. These devices are not just recording data but are capable of real-time analysis, enabling early detection of anomalies and facilitating timely interventions.
For instance, BioMan's AI Smart Clothing comes equipped with wearable electrodes combined with modern information technology to provide vital sign monitoring. Another example is Preventice's BodyGuardian Remote Monitoring System, which oversees key biometrics in individuals with non-lethal cardiac arrhythmias.
Chronic Disease Management
Chronic conditions like diabetes, cardiovascular disease, and hypertension require continuous monitoring, which is where smart wearables excel. These devices can track a range of metrics from glucose levels (via wearable patches) to cardiac rhythms (through smartwatches with ECG capabilities). The seamless integration of wearables into daily life makes them particularly suited for chronic disease management, reducing the need for frequent hospital visits.
A notable example is the Guardian Connect from Medtronic, a glucose monitoring wearable that provides real-time data and alerts, aiding in the management of diabetes.
Remote Patient Monitoring
Remote Patient Monitoring (RPM) systems have been revolutionised by the advent of wearables. These systems facilitate continuous monitoring of patients in non-clinical settings, relaying crucial health data to healthcare providers. This transformation enhances patient care, reduces hospital readmissions, and alleviates the burden on healthcare systems.
For instance, BodyTel's suite of products, including a blood glucose metre, blood pressure metre, and scales, allows for comprehensive home diagnostics and telemedicine applications.

For wearables to realise their full potential, the data they generate must be integrated into healthcare providers' ecosystems. This integration would enable clinicians to access comprehensive patient data, facilitating more informed decision-making. Interoperability standards and regulatory frameworks must evolve to support seamless data exchange between wearables and electronic health records (EHRs).
For instance, Apple's wearable patch, designed to monitor glucose levels and other metabolic functions, has the potential to integrate seamlessly with existing healthcare infrastructure, provided that interoperability issues are addressed.
Real-World Applications and Case Studies
Numerous case studies illustrate the transformative impact of wearables on healthcare. One such example involves monitoring and managing Parkinson's disease. In collaboration with Michael J. The Fox Foundation and Intel have developed a comprehensive monitoring system that collects extensive data on Parkinson's patients. This data is then analysed to identify symptom patterns, contributing to improved disease management and treatment personalization.
Wearables in Hospital Settings
Wearables are increasingly finding applications in hospital settings, enhancing patient monitoring and streamlining workflows. Devices like the NuMetrix Heart Sensing Sports Bra, which incorporates electrical sensing technology to monitor heart activity, can provide continuous data, reducing the need for manual monitoring and freeing up healthcare resources for other critical tasks.
Home-Based Health Monitoring
For elderly patients and individuals with mobility issues, home-based health monitoring facilitated by wearables offers significant benefits. Devices like PERSmobile by Everton provide security and mobility to the ageing population, offering emergency alerts and continuous health monitoring, thus allowing elderly individuals to live independently while maintaining a safety net.
