Our expert team tests and 
validates your wearables.

The Valencell Biometrics Lab is one of the most sophisticated wearables research labs in the world.

Valencell’s Biometrics Lab puts your wearable product or prototype through a battery of testing protocols and activity sets. We then analyze and validate the data to determine real-world accuracy and identify improvements to product design and performance.

Key use cases include: exercise, activities of daily living, prevention, chronic disease management, clinical vital signs monitoring, and clinical research. 

Both in-lab and naturalistic settings are supported.

Reference devices include benchmarks for: heart rate, heart rate variability (HRV), breathing (respiration) rate, VO2, calories burned, blood pressure, physical activity, pulse-oximetry, step count, step rate, and more.

 A diversity of form-factors have been evaluated: wrist, arm, finger, earpieces, headgear and headsets, patches, leg-worn devices, and smart apparel.  


Valencell Biometrics Lab

We test over 400 different devices per year from the leading wearable tech companies. Annually the Lab:

  • Conducts over 36,000 different device tests
  • Analyzes over 50 million biometric data points
  • Measures over 2,000 hours of testing & validation
  • Performs over 2500 blood pressure tests


The only way to bring a successful and accurate device to market is through intensive testing and validation. Everyone has different physiological characteristics, yet devices must provide consistent and accurate data across a wide range of people doing a variety of activities at different intensity levels. We use dozens of different protocols in our testing methodologies to account for these differences and will customize testing protocols to match the intended user experience.


  • Walking, jogging, running, biking, rowing, gym exercises, lifestyle activities, & more
  • Medical use cases using blood flow dynamics and deep features of the PPG waveform for medical insights 
  • Steady-state, dynamic pacing, and high-intensity interval training (HIIT)
  • Indoor, outdoor & aquatic testing
  • Test subjects vary by age, sex, fitness levels, skin tones & body types
  • Metrics measured include heart rate, breathing (respiration) rate, RR-interval (RRi), physical activity parameters, blood pressure, blood oxygenation, blood glucose level, and VO2
  • Assessments include V02 max, cardiac efficiency, recovery time, heart rate variability, ventilatory threshold, and lactate threshold
  • Both in-lab and naturalistic settings are supported

Thinking Ahead

The Lab also contributes to Valencell’s research and development of new technology related to physiological biometrics as applied to fitness, exercise, personal health, and military situations. Beyond our own technology, we continually evaluate biometric wearable products that are not powered by Valencell to identify strengths and weaknesses of all technologies and products on the market today.
