摘要：
A system for detecting artery location to measure blood velocity includes a first piezoelectric transducer array including a plurality of transducer elements, each of the transducer elements being supported on a first ceramic substrate, the first ceramic substrate having a planar lower surface configured to be placed on a surface of an area of skin of a user, the first ceramic substrate being configured to couple an ultrasonic signal emitted by the transducer elements to the skin. A phase control system is configured to supply each of the transducer elements with an electrical actuation signal, the electrical actuation signal being phase shifted for each of the transducer elements. The phase control system is configured to phase shift the electrical actuation signal supplied to the transducer elements such that an ultrasonic beam is formed and to steer the ultrasonic beam toward a blood vessel located beneath the area of skin.
