    Abstract: An ultrasound transducer unit includes: a plurality of units each of which includes a piezoelectric element group, a wiring substrate that includes a plurality of wiring lines that are electrically connected to piezoelectric elements included in the piezoelectric element group, and a cable group that is electrically connected to the wiring lines included in the wiring substrate, that extends in a direction intersecting a longitudinal direction of each of the piezoelectric elements included in the piezoelectric element group, and that is formed into a helical shape; an outer surface support that supports, by using an outer surface of the outer surface support, the piezoelectric element group included in each of the plurality of units; and an inner surface support that supports an inner surface of the outer surface support. Cable groups included in the plurality of units constitute a multiple helical structure.

    Abstract: An ultrasound transducer includes a transducer body configured to generate ultrasound vibration to vibrate a treatment portion that treats a living tissue. The transducer body includes a plurality of piezoelectric elements configured to alternately repeat expansion and contraction according to a supplied drive signal. The plurality of piezoelectric elements are integrally fastened in a state where the plurality of piezoelectric elements are stacked along a direction of expansion and contraction. The plurality of piezoelectric elements include a first piezoelectric element configured to expand at a first timing and contract at a second timing, and a second piezoelectric element whose expansion and contraction timings are different from expansion and contraction timings of the first piezoelectric element. The second piezoelectric element is arranged so that a polarization direction of the second piezoelectric element is a same as a polarization direction of an adjacent piezoelectric element.

    Abstract: An embodiment herein provides an apparatus for generating and transmitting ultrasonic waves into a non-planar target for one or more applications. The apparatus includes a control system that generates one or more electrical signals, and a transducer assembly including one or more transducers that receive and convert the one or more electrical signals into the ultrasonic waves. The generated ultrasonic waves are efficiently transmitted into the non-planar target in one or more directions by reducing surface mismatch, where the ultrasonic waves cause at least one of an acoustic streaming, a cavitation, a microstreaming, standing waves, a turbulence in a flow of fluids, a vibration of fluid molecules, a vibration of solids, reflection, refraction, or absorption, thereby improving efficiency of the one or more applications comprising any of, but not limited to, cleaning, imaging, mixing, measuring, sensing, or therapy.

    Abstract: A method for controlling a system, comprising repeatedly monitoring at least one operational characteristic of a system that includes an ultrasonic transducer, wherein the ultrasonic transducer is powered by an ultrasonic generator and is configured to drive a device at predetermined levels of vibration amplitude, and wherein the ultrasonic generator includes a controller configured to monitor operational parameters of the system; detecting a change in an operational characteristic based on a comparison of the monitored characteristic against a predetermined threshold for that characteristic; inferring a system-use criteria based on the detected change in the operational characteristic; and adapting system control by using the controller to alter the operational characteristic based on the inferred use criteria.

    Abstract: An ultrasonic sensor includes an ultrasonic transducer; a first voltage output circuit to output a transmission voltage signal that oscillates between a first high voltage and a first low voltage, supplied to a first terminal of the ultrasonic transducer; a reception circuit to detect a voltage signal generated at a second terminal of the ultrasonic transducer; and the second voltage output circuit to output a second high voltage smaller than the first high voltage. The first voltage output circuit includes a first switching unit to perform switching between supplying the transmission voltage signal in ultrasonic transmission; and fixing a potential of the first terminal in ultrasonic reception. The second voltage output circuit includes a second switching unit that performs switching between supplying the second high voltage to the second terminal in ultrasonic transmission; and electrically separating the second voltage output circuit from the second terminal in ultrasonic reception.
