Lots of folks have been asking me how  V-LINC™ technology can deliver real-time biometric and physiological data. The technology consists of three novel elements:

1) Sensor module designs

2) Signal extraction technology 

3) Physiological assessments

Valencell has designed a highly miniaturized sensor module  that is capable of fitting inside virtually any earbud or audio headset. The sensor module shines light into the ear region and measures how this light interacts with blood flow. 

This information is then processed by novel signal extraction algorithms to pull out blood flow information (which is actually very faint) from what amounts to be an incredible amount of noise.  For example, the signal from blood flow is more than 100-1,000 times weaker than the signal coming from motion noise and environmental noise (like sunlight).   

Next, Valencell’s novel algorithms process this information into important vital signs metrics, such as heart rate, respiration rate, energy expenditure, and more. These vital signs metrics are then sent wirelessly to select smartphone applications (Android and iOS devices) that generate real-time   fitness assessments such as  resting heart rate, trainling load, VO2max, personalized heart rate zones, and recovery time. 

Seamless integration of V-LINC™ technology within mobile devices makes it ideal for use in fitness training, athletic performance coaching, and many other related applications. If this gets you interested, be sure to look for headsets and earbuds that are powered with V-LINC™ tech.
