Biostrap utilizes a clinical-quality PPG sensor with RED and InfraRed LEDs, whereas FitBit (and most of the other wearables) use GREEN LEDS.
Red & IR are capable of penetrating much deeper into the tissue which helps us get very high-definition pulse waveform. Another advantage of infrared light over green is that it is less sensitive to skin tone variations and perfusion levels due to its better tissue penetration characteristics. In fact, most of the medical-grade devices use similar technology.
We use the high-definition pulse to derive various vital biometric markers using complex patented algorithms. Currently, we capture Heart Rate, Heart Rate Variability, Respiration, and Oxygen Saturation, and more to come in near future.
Green LEDs on the other hand, are more resilient to motion and light exposure, therefore can read active HR. But can not penetrate deeper, and therefore can’t gather biometric data at the accuracy Biostraps' red and NIR optical sensors can.
So it is a trade-off between getting accurate biometric reading versus active HR. We do, however, offer two types of heart rate monitors, which you can use to measure active HR during your workouts.
Does Biostrap track active heart rate?
Short answer is: YES, you can see active HR in the Biostrap app with an external heart rate monitor! With the wristband device by itself, it’s important to note that we don’t currently take continuous or real-time measurements - including measuring ...
How do I pair my external heart rate monitor (HRM) to Biostrap for active heart rate?
We're super excited to have this integrated solution for active heart rate! We released this for iOS in September 2017, and released it for Android in March 2018. We have successfully tested with the following devices: Polar H7 Polar H10 Polar OH1 ...
How can Biostrap track or recognize any exercise or activity?
Biostrap can be made to learn any repetitious activity. With our wristband-shoeclip pairing, Biostrap provides comprehensive data unmatched by other wearable products on the market. We monitor heart rate, blood oxygen saturation, respiratory rate, ...
What do the Biostrap wristband and activity pod track?
Your Biostrap wristband and activity pod can track your daily biometrics and activities. The Wristband records your steps, sleep, calories burned, resting heart rate, heart rate variability, respiratory rate and blood oxygen saturation. Biostrap's ...
How can Biostrap measure respiratory rate?
With our clinical-grade wristband device, Biostrap can measure respiratory rate with an algorithm combining the following: Changes in amplitude of the PPG signal: As someone inhales and exhales, we review the signal changes Heart Rate Variability: ...
