Smartwatches have emerged as powerful health monitoring tools that combine communication, computing, and sensing capabilities. The Apple Watch earned its first FDA approval in 2018 when it added a feature to detect irregular heart rhythms, including atrial fibrillation. These devices can now perform electrocardiograms, detect falls, monitor blood oxygen levels, and track various other health metrics.

Inertial measurement unit-based sensors were used in 67% of studies, with wrist-worn devices being the most common at 65%. The popularity of wrist-worn devices stems from their convenience, user acceptance, and ability to capture a wide range of physiological and activity data.

Medical-Grade Monitoring Devices

Medical-grade wearables are specialized devices designed for specific health conditions or remote patient monitoring, and are often prescribed by healthcare providers and require FDA clearance. These devices meet rigorous standards for accuracy, reliability, and clinical validity.

Examples include continuous glucose monitors for diabetes management, cardiac event monitors for arrhythmia detection, and specialized patches for post-operative monitoring. Medical patches provide continuous monitoring of ECG, heart rate, respiratory rate, and body temperature, with data sent instantly to a secure cloud platform, giving healthcare providers up-to-the-second data on patient health.

Biosensors and Adhesive Patches

Biosensors and patches are non-invasive sensors that track biometric data like heart rate, respiration, and temperature, and are often used in clinical settings for continuous patient monitoring. These devices offer the advantage of being unobtrusive while providing high-quality physiological data.

Recent innovations in this category include ultra-compact designs that minimize patient burden while maximizing data collection capabilities. The integration of highly wearable, sensor-packed devices that collect real-world, real-time health data reflects a growing trend in clinical research, as decentralized and hybrid clinical trials become more common, helping improve patient compliance while enhancing the granularity and reliability of data.

Newer sensors can integrate right into textiles, making compliance as easy as getting dressed in the morning, from compression garments that monitor lymphedema to socks that detect diabetic foot ulcers. These innovations represent the future of seamless health monitoring.

The Growing Adoption of Wearables in Clinical Research

The integration of wearable devices into clinical research has accelerated dramatically in recent years, driven by technological advances and recognition of their potential to improve trial quality and efficiency.

Current Adoption Rates and Trends

Approximately 2.2% of clinical trials in high-income countries have incorporated wearables since the start of 2020. While this percentage may seem modest, it represents significant growth from earlier years and continues to accelerate.

The utilization of wearable devices for data collection and behavioral interventions in various disease areas has been increasing over time since 2012, with the increase in the number of studies over the past 3 years being particularly significant, suggesting that this trend will continue to accelerate in the future.

Therapeutic Areas Leading Adoption

Adoption is highest in development programs that struggle to assess 'function in daily life' for patients using traditional clinical outcome assessments, such as neurology, pulmonology, cardiology, and rheumatology. These therapeutic areas benefit particularly from continuous, objective monitoring of patient function in real-world settings.

Most studies used device data to monitor a chronic disease at 85%, most often neurodegenerative at 32%, while 15% used device data to diagnose new disease, majority being cardiovascular at 75%. This distribution reflects both the capabilities of current wearable technology and the clinical needs in different disease areas.

Recent Regulatory Approvals and Market Developments

The regulatory landscape for wearable medical devices has evolved rapidly, with numerous approvals demonstrating the maturation of the field. Recent FDA clearances highlight the breadth of applications:

In September 2025, Biolinq received FDA De Novo Classification for Biolinq Shine™, a forearm patch wearable biosensor for non-insulin type 2 diabetes patients, tracking glucose, activity, and sleep.

These approvals demonstrate the increasing sophistication of wearable technology and regulatory acceptance of these devices for critical clinical applications.

Comprehensive Benefits of Wearable Devices in Clinical Evaluations

Wearable devices offer numerous advantages that address longstanding limitations of traditional clinical assessment methods. These benefits extend across multiple dimensions of clinical research and patient care.

Continuous and Comprehensive Data Collection

One of the most significant advantages of wearable devices is their ability to provide continuous monitoring over extended periods. Traditional physiological data such as vital signs and telemetry are collected only during doctor's office visits or as part of medical product clinical trial procedures, representing a very limited snapshot of a person's phenotype and physiology.

Longitudinal data can be gathered over an extended period, offering a better grasp of an individual's condition and the effectiveness of treatment. This temporal depth enables researchers and clinicians to identify patterns, trends, and variations that would be impossible to detect through periodic assessments alone.

Compared to traditional sporadic clinic visits, continuous monitoring generates a more comprehensive data set, encompassing physiological, movement, and sleep biometrics. This multidimensional data provides a holistic view of patient health and functioning.

Real-Time Monitoring and Objective Data

With their capacity for real-time, objective data collection and continuous monitoring, wearable devices stand as conduits that effortlessly capture patients' experiences, unburdened by the recall biases that can plague traditional approaches. This objectivity is particularly valuable in clinical trials where subjective reporting can introduce variability and bias.

At-home data collection allows for objective real-time data that reflect the patients' daily activities. This real-world evidence is often more representative of actual patient experiences than data collected in artificial clinical settings.

Enhanced Patient Engagement and Compliance

Wearable devices can significantly improve patient engagement in their own health management and clinical trial participation. By providing immediate feedback and making health data visible and accessible, these devices help patients become active participants in their care.

Wearable devices offer clear advantages in terms of data consistency and patient engagement. Patients who can see their own health metrics in real-time often demonstrate better adherence to treatment protocols and lifestyle modifications.

These innovative tools make vast improvements to healthcare outcomes, allowing a more granular look at a patient's vitals and facilitating more patient engagement in their own health, providing continuous monitoring, early disease detection, and personalized treatment options.

Reduced Burden on Patients and Healthcare Systems

Wearables have the added benefit of remote monitoring, thereby decreasing the necessity for frequent in-person visits. This reduction in clinic visits benefits both patients and healthcare systems by decreasing travel burden, reducing costs, and freeing up clinical resources.

Wearable devices collect data that allow novel insights while helping sponsors complete trials faster and with fewer participants. This efficiency can accelerate drug development timelines and reduce the overall cost of bringing new treatments to market.

Improved Accuracy and Clinical Insights

Having larger and denser datasets helps to characterize intra- and interpatient variability. This enhanced understanding of variability enables more precise patient stratification and personalized treatment approaches.

There is growing evidence that replacing paper diaries with electronic versions can greatly improve the quality of subjectively reported outcome data, such as pain and functional status, by ensuring compliance, timely collection of the data, avoidance of secondary data entry errors, and reduced administrative burden.

Real-world examples demonstrate these benefits. Studies have found that active tests detect significant disease-like symptoms, and by passively collecting raw data while patients go about their daily activities, researchers obtain enormous, rich datasets that provide unique additional insights using machine learning, showing strong correlation between remotely collected sensor signals and clinical assessments.

Multi-Dimensional Health Assessment

Wearables can capture diverse data, encompassing physiological, movement, and sleep metrics, providing a more profound understanding of the multifaceted factors influencing a patient's health, which may change in response to a new treatment.

Wearable device data combined with other data such as genomics or other high-throughput technologies have the potential to create a comprehensive multilayer picture of a person's health and can deepen our understanding of how to combine genotyping with deep phenotyping. This integration of multiple data streams represents the future of precision medicine.

Critical Challenges and Limitations

Despite their considerable promise, wearable devices face several significant challenges that must be addressed to maximize their potential in clinical evaluations. Understanding these limitations is essential for appropriate implementation and interpretation of wearable-derived data.

Data Privacy and Security Concerns

The continuous collection of health data raises important privacy and security considerations. Patient data collected during clinical trials fall under the Health Insurance Portability and Accountability Act (HIPAA), which regulates how protected health information can be used and shared, however, consumer-grade devices are regulated differently, where rules pertaining to data protection are largely up to the manufacturers, leading to potential ethical and legal concerns.

Healthcare organizations must ensure that wearable data collection, transmission, and storage meet stringent security requirements. The risk of data breaches, unauthorized access, and misuse of sensitive health information requires robust cybersecurity measures and clear data governance policies.

Device Accuracy and Validation

The accuracy and reliability of wearable devices vary considerably across manufacturers and device types. Commercial fitness trackers collect mobility and some vital sign data, but similar wearables cannot be marketed as medical devices unless the device performance has been established prior to release to the market.

Challenges remain in sensor placement standardization, data processing consistency, and real-world validation. These technical challenges can affect the reliability of data collected in clinical settings and must be carefully considered when designing studies or making clinical decisions based on wearable data.

Another issue with wearable devices lies within the proprietary nature of the algorithms and data ownership, as many wearable manufacturers don't allow researchers to directly access the raw data and give partially redacted descriptions of the acquisition and processing method, which means the accuracy of the data acquired for clinical trials might be compromised.

Patient Compliance and Usability

The effectiveness of wearable devices depends heavily on consistent patient use. Feasibility determinants were inconsistently reported, including compliance at 64%, patient-reported useability at 16%, and participant technology literacy at 1%. This inconsistent reporting makes it difficult to assess the real-world feasibility of wearable-based interventions.

Factors affecting compliance include device comfort, battery life, ease of use, and the burden of charging and maintaining devices. Older adults or those with limited technological literacy may face particular challenges in using wearable devices effectively.

Cost and Accessibility

The cost of wearable devices can be a significant barrier to widespread adoption. While consumer-grade devices have become more affordable, medical-grade wearables often carry substantial costs. These devices are generally not covered because they are considered to be for health and fitness purposes and not medically necessary, although Medicare Advantage plans may offer limited coverage.

This lack of reimbursement creates disparities in access and may limit the generalizability of clinical research that relies on wearable technology. Ensuring equitable access to wearable-based healthcare interventions remains an important challenge.

Regulatory and Standardization Issues

Researchers face many challenges in the clinic, including scientific methodology as well as regulatory, legal, and operational hurdles. The regulatory landscape for wearable devices continues to evolve, creating uncertainty for manufacturers and researchers.

Wearable devices that provide users with statistics like step counting, calorie tracking, workout tracking, and basic heart rate monitoring are able to escape FDA's purview, however, once devices add Electrocardiogram features intended to detect irregular heart rhythms, provide feedback based on heart rate and motion data during sleep, and ways to detect sleep apnea, they are beholden to medical device regulations.

This regulatory complexity can slow innovation and create confusion about which devices are appropriate for clinical use. Most medical-grade wearables fall under Class II and require a 510(k) premarket notification, and developing such devices means following IEC 62304 software lifecycle standards and maintaining detailed design and risk documentation.

Data Integration and Interoperability

Interoperability and integration with existing healthcare systems pose challenges, as wearables generate vast amounts of data that need to be seamlessly integrated into electronic health records and other clinical systems, requiring standardization of data formats and protocols to ensure smooth data exchange between wearables and healthcare platforms.

The lack of standardized data formats and communication protocols makes it difficult to aggregate data from multiple device types or integrate wearable data into existing clinical workflows. This fragmentation limits the utility of wearable data in comprehensive health assessments.

Limited Evidence of Clinical Effectiveness

Evidence for clinical effectiveness of wearable devices remains scant, and heterogeneity across studies in terms of devices, disease targets and monitoring protocols makes data synthesis challenging, especially given the rapid pace of technical innovation.

Only 8% of studies were randomized controlled trials, with 67% showing evidence of positive clinical impact. While promising, this limited high-quality evidence base means that many applications of wearable technology in clinical settings remain investigational.
