Advanced Biosensors, In-Depth Analysis, Clinically Validated Biometrics
Photoplethysmography (PPG)
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. Sensor Bio provides precise measurements of important health biometrics through complex analysis of the PPG waveform.
Accelerometer & Gyroscope
Built-in accelerometer and gyroscope sensors capture reliable motion data for comprehensive physical activity and sleep analysis and assist in the removal of motion artifacts in the PPG signal.
One Platform Connecting Every Ecosystem
The Sensor Bio platform serves as a centralized integration hub, enabling interoperability across clinical, institutional, and consumer-facing environments. Processed biosignal data is accessible to external applications, EMR/EHR systems, wellness platforms, and hospital networks via standardized API interfaces. Mobile connectivity is established through SDK integration and Bluetooth Low Energy (BLE) protocols, allowing clinicians, researchers, and end users to access physiological metrics within their existing workflows.
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. Sensor Bio provides access to raw and/or processed PPG, gyroscope, and accelerometer data to researchers via the RPM dashboard.
Advanced cloud processing & data architecture
The Sensor Bio 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 to not affect outcome measures.
High-fidelity biosignals recorded by Sensor Bio biosensors are transferred to an Android/iOS mobile app via Bluetooth and stored in Sensor Bio cloud servers for data processing, then delivered back to the mobile app and remote physiological monitoring (RPM) web dashboard for analysis.
Advanced Biometrics
From each PPG waveform measurement, the Sensor Bio Pulse Engine™ extracts vital biometrics such as heart rate, heart rate variability, 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.
Novel Biometrics
At Sensor Bio, we believe that the PPG waveform contains much more physiological information yet to be discovered. Stay tuned as we continue to push the boundaries of biometric data science to derive additional health metrics.
Clinical Validation
Data integrity is critical when relied upon for remote monitoring, risk stratification, and decision making. Learn more about Sensor Bio’s Validation Studies and Ongoing Research.
