Evolution of the clinically trusted TempTraq system

Welcome to VitalTraq™ the first-of-its-kind multi-sensor remote patient monitoring platform, that integrates one of the most groundbreaking contactless vital sign measurement sensors to date, Remote Photoplethysmography (rPPG). Using a simple 30 to 60-second selfie scan, patients, clinicians, and researchers can collect digital measurements, including Heart Rate, Heart Rate Variability, Blood Pressure, and Respiratory Rate vital signs in a single contactless patient experience.

Engineered to modernize continuous remote care for patients, VitalTraq integrates real-world data collection while minimizing patient and physician burden. Patients experience convenient care by combining Blue Spark’s market-leading core body temperature wearable TempTraq® sensor and contactless rPPG facial scanning in a single, easy-to-use mobile application. Using groundbreaking, clinically validated Remote Photoplethysmography technology, patients scan their faces for a reading that captures blood flow patterns and translates them into vital sign measurements in a single remote monitoring platform. Combining the two technologies on a patient’s own device dramatically reduces the number of devices a patient needs while also reducing device distribution logistics on health care providers. rPPG sensing is currently available on the VitalTraq platform under investigational use only.


VitalTraq captures periodic vital signs without needing additional wearables or related apps utilizing the camera on a standard smartphone or tablet.

Measures vital signs including:

  • TempTraq core body temperature
  • Heart Rate
  • Heart Rate Variability
  • Blood Pressure
  • Respiratory Rate
  • + additional sensors available upon request

What VitalTraq Sees

Patient Application – rPPG Measurement

rPPG stands for “remote photoplethysmography.” It is a non-contact method of measuring a person’s vital signs, such as heart rate and respiratory rate. rPPG works based on light absorption and reflection from the skin. Blood absorbs light and becomes more or less translucent depending on the blood volume. When your heart beats, your blood vessels expand and contract, which affects the amount of light absorbed and reflected by the skin. VitalTraq™ uses the front camera on a compatible device to perform an rPPG facial scan to capture blood flow patterns, which are then translated into vital sign measurements.

  • Cell phone or tablet camera – compatible with iPhone and Android
