Abstract
Provided are apparatuses and methods for non-invasively measuring a blood pressure of a mammal subject. The apparatus includes a first sensor system and a second sensor system time-synchronized to each other and spatially separated by a pulse arrival distance L, and a microcontroller unit (MCU). The first and second sensor systems are respectively attached to first and second positions of the mammal subject for detecting first and second signals. The second position is more distal or proximal to a heart of the mammal subject than the first position. The MCU processes the output signals to determine a pulse arrival time (PAT) as a time delay Δt between detections of the first and second signals, and determines a pulse wave velocity (PWV) based on the PAT and L, where Then the MCU determines the blood pressure P from the PWV, where P is a parabolic function of the PWV.
