Use your smartphone's camera to measure body's vital signs such as heart rate, mental stress, oxygen saturation or respiration.
No skin contact or wearable devices are required.
What is rPPG ?
Binah.ai developed an advanced set of algorithms, which provide measurements of person’s vital signs by using a camera, which are based on rPPG or PPG (which is based on finger measurements).
rPPG - Remote Photoplethysmographic imaging is a camera-based solution for non-contact cardiovascular monitoring from a distance. This technology enables monitoring in situations where contact-based devices may be challenging or infeasible, such as ambulatory, sleep, and multi-individual monitoring.
More information about rPPG can be found at: https://en.wikipedia.org/wiki/Photoplethysmogram#Remote_ photoplethysmography
Binah.ai measures the person’s heart-rate, oxygen saturation, respiration and heart rate variabilities (HRV) by reconstructing the rPPG signal from the Smartphone camera using a signal processing, and not by a statistical estimations, and without the need to use any additional sensors.
Binah.ai’s technology was validated by our customers in official clinical trials of more than 800 people and found that our rPPG based HRV is statistically equal to the PPG based HRV using the CoreSense oximeter by Elite HRV.
By having an accurate HRV, we can calculate a person’s mental stress level by using Baevsky’s research which can be found here: https://www.researchgate.net/publication/317227023_Heart_rate_variability_analysis_physiological_ foundations_and_main_methods/fulltext/59334b1da6fdcc89e7cf2097/Heart-rate-variability-analysis-physiological- foundations-and-main-methods.pdf
We are using Baevsky’s mental stress index to calculate the person’s mental stress into 5 levels (Low, Normal, Mild, High, Extremely high).
