摘要:
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 substrate, a transducer element attached to 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. A tilt control system 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.
