Pulse Engine

Pulse Engine

Biostrap’s proprietary pulse engine assesses each pulse wave versus 29 unique parameters to provide processed data with the highest data integrity and reliability.

Pulse Engine 1

Photoplethysmography

Photoplethysmography

Photoplethysmography, or PPG, 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 a complex analysis of the PPG waveform.

Wavelength Matters

Wavelength Matters

Biostrap uses a proprietary IR/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.

Data Architecture

Data Architecture

Raw bio-signals recorded by Biostrap biosensors are transferred to an Android/iOS mobile app via Bluetooth and stored in Biostrap cloud servers for data processing. Processed data is then delivered back to the mobile app and remote patient monitoring (RPM) web-application for analysis.

Raw Waveform Data

Raw Waveform Data

Most wearables discard raw waveform data to improve calculation speed- but sacrifice data quality and integrity. Saving raw waveform data enables in-depth analysis of health biometrics using powerful cloud-based algorithms. Biostrap provides access to raw and/or processed PPG, gyroscope, and accelerometer data to researchers via the RPM dashboard.

Pulse Engine 3

Advanced Cloud Processing

Advanced Cloud Processing

The Biostrap Pulse Engine ™ is a cloud-based computational tool that filters, cleans, processes, and analyzes PPG waveform data to obtain various metrics. Motion artifacts and irregular waveform patterns are filtered out as to not affect the outcome measures.

Advanced Biometrics

Advanced Biometrics

From each PPG waveform measurement, the Pulse Engine extracts vital signs like heart rate, heart rate variability, oxygen saturation, and respiratory rate. In addition, the Pulse Engine does in-depth analysis of every heart beat it detects to obtain cardiovascular metrics such as arterial and peripheral elasticity, as well as various beat shape features for use in detecting particular conditions or diseases.

At Biostrap, we believe that the PPG waveform contains much more physiological information yet to discover. Stay tuned as we continue to push the boundaries of biometric data science to derive additional health metrics.
