Biostrap

Biostrap is an advanced wearable tracking device that uses Photoplethysmography, or PPG, that measures changes in blood volume caused by the heart’s pumping action by illuminating the skin with a light-emitting diode (LED) and measuring changes in light absorption with a photodetector. Biostrap provides precise measurements of important health biometrics through complex analysis of the PPG waveform.

​

Biostrap uses a proprietary Infra Red/Red optical sensor that captures high signal-to-noise and high-resolution PPG measurements from deep beneath the skin (up to 10x deeper than green light) to extract reliable biometrics. The Biostrap PPG signal is not affected by high melanin content or skin tone, tattoos, or other physiological variations that impact the reliability of other PPG devices which use a green light source.

​

Each devices have a built-in accelerometer and gyroscope sensors that capture reliable motion data for comprehensive physical activity and sleep analysis and assist in the removal of motion artifacts in the PPG signal.

 

​From each PPG waveform measurement, the Biostrap Pulse Engine™ extracts vital biometrics such as heart rate, heart rate variability, oxygen saturation, and respiratory rate. The Pulse Engine™ also performs an in-depth analysis of every detected heart beat to obtain cardiovascular properties including arterial and peripheral elasticity along with additional beat shape features that can be utilized for assessing various health conditions or diseases.
