of Science

This Optical Blood Pressure Monitoring (OBPM®) technology analyses photoplethysmographic (PPG) signals acquired at your wrist to estimate blood pressure, with no pain or inflation. These PPG signals are recorded by illuminating your skin with a tiny green light, and by further capturing the light that is scattered and modulated by the pulsation of your skin arterioles. These signals carry important information such as Heart Rate and Blood Pressure.

But where do these signals come from? At each cardiac cycle, the heart contracts, the aortic valve opens, and blood is pumped into the aorta. A pressure pulse is thus generated that propagates along the walls of the arterial tree and is partially reflected backwards when it encounters an at arterial branching or tapering. The superposition of the pressure pulses creates one's pressure pulse mixture, which contains important information on the individual's arterial tree topology, cardiovascular status, and blood pressure. This precious information is carried within the arterioles walls, captured by the PPG signals and finally decoded by the OBPM® algorithms of Aktiia.

We are proud to state that our technology has been validated in several pilot studies and clinical trials. You can find the updated list of trials here:
