Abstract
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° and less than 90°. 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.
