Abstract: Some implementations of the disclosure describe a blood pressure measurement apparatus and method that enable continuous, non-invasive blood pressure measurement using sound and ultrasound transducers. In one implementation, a blood pressure measurement device includes: a first transducer configured to emit multiple soundwaves having multiple frequencies, the soundwaves configured to cause a blood vessel of a subject to vibrate; a second transducer configured to capture one or more ultrasound images of the blood vessel; and a processing device configured to: determine, based on the one or more ultrasound images, a wall thickness, a radius, and a resonant frequency of the blood vessel; and calculate, based on the wall thickness, the radius, and the resonant frequency, a blood pressure of the subject.
