A system for detecting blood velocity within a blood vessel includes a piezoelectric transducer supported on a ceramic substrate. The ceramic substrate supports the piezoelectric transducer at a fixed angle of incidence that is greater than 0&#xb0; and less than 90&#xb0;. The ceramic substrate is formed of steatite ceramic and is configured to couple an ultrasonic signal emitted by the transducer to skin underlying the substrate.

Single piezoelectric transmitter and receiver to detect blood velocities

A system for detecting blood velocity within a blood vessel includes a transducer array including a plurality of transducers. Each of the transducers includes a carrier substrate, at least one spacer extending upwardly from the substrate, a transducer element attached to the spacer such that the piezoelectric transducer is spaced apart from the substrate, and setting electrodes positioned on the upper surface of the substrate under the piezoelectric transducer. The system also includes a tilt control system that is configured to apply a bias voltage to the setting electrodes which causes the transducer element to pivot about a pivot axis between a first tilted position and a second tilted position.
