摘要： A first lamination step of forming lower electrode films on both surfaces of a diaphragm and directly forming a first Pb-containing perovskite oxide film which has a larger thermal expansion coefficient than that of the diaphragm and has a columnar structure on a front surface of the lower electrode film; and a second lamination step of directly forming a second Pb-containing perovskite oxide film on a front surface of the lower electrode film are sequentially performed. The second Pb-containing perovskite oxide film is formed under a condition that a difference between a molar ratio RA1 of Pb to a B-site element in the first Pb-containing perovskite oxide film and a molar ratio RB1 of Pb to a B-site element in the second Pb-containing perovskite oxide film after the second lamination step is 0.056 or less.

摘要： Rotational intravascular ultrasound (IVUS) imaging devices, systems, and methods are provided. Some embodiments are directed to transducer mounting configurations that enable polymer piezoelectric micro-machined ultrasonic transducers (PMUTs) to be used with a Doppler color flow rotational IVUS imaging system. In one embodiment, a rotational intravascular ultrasound (IVUS) device includes: a flexible elongate body; a piezoelectric micromachined ultrasound transducer (PMUT) coupled to a distal portion of the flexible elongate body; and an application-specific integrated circuit (ASIC) coupled to the distal portion of the flexible elongate body. The ASIC is electrically coupled to the PMUT and includes a pulser, an amplifier, a protection circuit, and timing and control circuitry for coordinating operation of the pulser, amplifier, and protection circuit. The PMUT transducer is mounted with a tilt angle such that the IVUS catheter can be used to collect Doppler ultrasound blood flow data in conjunction with the IVUS imaging.

A first sensor is a motion sensor including a conductive liquid in a chamber between a rigid tube and a piezoelectric motion film circumferentially wrapped about the tube. A second sensor is a traditional acoustic sensor or a novel acoustic sensor using a piezoelectric sensor mounted with a thin film separation layer of flexible microspheres on a rigid substrate. Additional non-acoustic sensors are optionally mounted on the rigid substrate for generation of output used to reduce noise observed by the acoustic sensors. Combinations of acoustic, non-acoustic, and motion sensors co-located in rigid streamer housing sections are provided.

摘要： The present disclosure provides methods and apparatus of fabricating a transducer for use in ultrasound imaging. A substrate is provided. The substrate may be a silicon substrate having a first side and a second side opposite the first side. A transducer membrane is formed over the first side of the substrate. The transducer membrane includes a piezoelectric component. A well is formed in the substrate from the second side. A backing material is dispensed onto a first sidewall of the well in a manner so as to create a capillary effect that causes the backing material to wick down the sidewall, across the back side of the substrate exposed by the well, and up a second sidewall of the well. The transducer membrane is deflected so that the transducer membrane has a concave shape.
