Track your heart rate through your ears.
Valencell and FIIL have developed the Carat Pro Wireless Earphones. It uses PerformTek (ultra-miniaturized optomechanical sensor module) technology inside the earbud to monitor biometrics including heart rate, volume of oxygen (VO2) and maximal volume of oxygen (VO2max), resting heart rate cardiac efficiency, heart rate variability assessments, and calories burned.
“The sensor includes an optical emitter, an optical detector, specialized optomechanics, and an accelerometer,” according to Valencell.
Specifically, the sensor is designed with Photoplethysmography (PPG) technology to measure blood flow signals and translate them into a pulse rate.
Similar to the traditional PPG approach, the PerformTek sensor uses an optical emitter to shine light on the skin. Using a photodetector, it senses the scattered light and measures weak blood flow signals.
“The key differences are Valencell’s patented optomechanics and signal extraction methodologies, which employ active signal characterization to actively remove optical signals associated with motion artifacts (such as skin motion and footsteps) and environmental exposure (such as sunlight) from the photodetector,” according to Valencell.
These earphones also act as a coach while the user completes one of five exercises: running, biking, walking, yoga, and indoor training.
The biometric sensor technology is powered by Valencell’s Benchmark sensor system.
