Ennova Health 2023 Winner of IoT Category in e-Health, Wearables and Robotics

Advanced UV Data Collection for Dermatology Clinical Trials

The Replior RaySense is a wearable light-exposure device that provides continuous measurement of ultraviolet, visible and infrared light, fully integrated with the Replior ePRO system. It enables accurate, contextual exposure data synchronized with patient-reported outcomes in clinical studies.

Reliable Data Collection

Replior UV sensors make tracking UV exposure easy by syncing with the Trial Online ePRO app. Patients don’t need to take any extra steps, ensuring continuous data flow as they go about their daily routines. This integration improves data quality and patient compliance.

Versatile and comfortable

Wearable as a wristband, clip, or necklace, the sensors are designed for everyday use.
Finger ring with 14 different brace sizes.
All accessories feature a secure click-fit connection to the sensor

Accurate, multi-spectrum data

Measures ultraviolet radiation (UVA + UVB), visible light across red, green and blue channels (RGB), and infrared (IR)

Tailored to trial needs

Customizable settings ensure data collection aligns with specific study protocols

Real-time alerts for safety

Personalized notifications and visual cues help participants proactively manage exposure levels

Increase Patient Compliance and Engagement

With Replior UV sensors and the Trial Online ePRO app, patients become active participants in the study. This connection between data collection and engagement improves study retention and patient compliance.

Single app integration

Requires only one app installation on the patient’s device, reducing burden for both patients and sites

Real-time data transfer

Sensor data is sent directly to the patient's smartphone via Bluetooth and then uploaded to the ePRO

Protocol support

Offers oversight tools to help ensure compliance with UV exposure limits

Personalized push notifications

Alerts patients as they approach UV exposure limits, with visual graphics to track their progress

Engagement-driven features

Gamification elements, like awards and badges, motivate patients by celebrating their progress and completed tasks

We selected the Replior solution because integrating the UV sensor with the study ePRO app simplified access and supported participant retention and engagement, while streamlining UV exposure monitoring for our study team.

Increase Quality and Depth of Research Findings

Replior’s UV sensors provide real-time data tailored for dermatology and rare disease studies, enabling research teams to gather comprehensive, relevant insights, such as:

Dermatological Research

Track UV exposure to assess skin health, sunscreen effectiveness, and treatment outcomes

Erythropoietic Protoporphyria (EPP)

Monitor light sensitivity to ensure patient safety and measure treatment responses

Xeroderma Pigmentosum (XP)

Collect critical data while keeping patients within safe UV exposure limits

Oncology Studies

Assess the impact of UV exposure on skin cancer progression and treatment efficacy

Lupus Research

Examine UV exposure effects on lupus symptoms to support better patient care

Polymorphic Light Eruption (PLE)

Gather precise UV sensitivity data to refine treatments and improve outcomes

Designed for Comfort and Durability

The sensor’s mechanical design is optimized for clinical studies, where wearing position affects measurements. Its low weight of just 7 g (0.25 oz) reduces sagging when worn, while wearing-style compensation ensures consistent data across positions. The compact 24 mm (0.95 in) design makes it discreet and comfortable to wear in public.

Extended battery life

Battery life of up to 3 months per charge. Easy charging via custom charge clip and USB-C.

Reliable data storage

Optional internal storage supports 6+ months of data, depending on configuration, while the sampling rate adapts dynamically to sunlight intensity to optimize accuracy and battery life.

Real-time, accurate data

Provides configurable 2-minute averaged logging of UVI (UVA + UVB), RGB and IR for accurate environmental exposure assessment, with data transmitted to the participant’s smartphone and uploaded via the Replior ePRO app.

Proximity, skin temperature & motion sensing:

Integrated proximity, skin temperature and accelerometer sensors detect when optical sensors are covered and sampling is invalid, and support assessment of user behaviour and compliance.

Dose calculation & insights

Accumulated exposure is calculated automatically from recorded data, with configurable daily and weekly UVI dose graphs and tailored thresholds and dose notifications.

Advancing Clinical Research with a Unified Sensor Portfolio

Replior’s UV sensors have been a trusted tool for monitoring light exposure to ensure patient safety and protocol adherence. With the addition of the Scratch Sensor, researchers can now capture behavioral insights alongside UV data. Together, these sensors give clinical teams a more comprehensive understanding of patient health—combining precise, device-reported data with patient-reported outcomes for deeper, actionable insights.
