Principle of Operation:


With each beat of the heart, the pulsation travels along the artery and create microscopic motions on the surface of the skin. 


Using radar, our sensor reads in these motions and translates them into a high fidelity arterial waveform which contains cardiovascular metrics.


Using machine learning, the arterial waveform is processed by our algorithms to extract pulse rate, blood pressure, and pulse wave velocity.
