Embodiment Construction

[0055] Hereinafter, the ultrasonic measurement device according to the present embodiment will be described based on the drawings.

[0056] [Configuration of Ultrasonic Measuring Device]

[0057] figure 1 It is a perspective view showing a schematic configuration of the ultrasonic measurement device 1 according to the present embodiment. figure 2 It is a block diagram showing a schematic configuration of the ultrasonic measurement device 1 according to the present embodiment.

[0058] Such as figure 1 As shown, the ultrasonic measurement device 1 of the present embodiment includes an ultrasonic probe 2 and a control device 10 electrically connected to the ultrasonic probe 2 via a cable 3 .

[0059] This ultrasonic measurement device 1 brings an ultrasonic probe 2 into contact with the surface of an object (for example, a living body), and sends ultrasonic waves from the ultrasonic probe 2 into the living body. Ultrasonic waves reflected by organs in the object (living bod...

Abstract

The invention provides an ultrasonic device that has high transmission / reception efficiency of ultrasonic waves, an ultrasonic module, and an ultrasonic measuring device. The ultrasonic device includes: a substrate provided with a first opening and a second opening; a support film that is provided on the substrate and closes the first opening and the second opening; a transmitting piezoelectric film that is provided on the support film at a position which overlaps the first opening when viewed in a thickness direction of the substrate and that is sandwiched between a pair of electrodes in thethickness direction of the substrate; and a receiving piezoelectric film that is provided on the support film at a position which overlaps the second opening when viewed in the thickness direction ofthe substrate and that is sandwiched between a pair of electrodes in an intersecting direction intersecting with the thickness direction of the substrate.

Description

technical field [0001] The invention relates to an ultrasonic device, an ultrasonic component, an ultrasonic measuring device and the like. Background technique [0002] Conventionally, as an ultrasonic transducer for transmitting and receiving ultrasonic waves, it is known to include a piezoelectric body sandwiched between a pair of electrodes, to transmit ultrasonic waves by applying a voltage between the electrodes to vibrate the piezoelectric body itself, or to transmit ultrasonic waves by An ultrasonic transducer of a so-called stacked piezoelectric body that detects an output voltage from a piezoelectric body to which ultrasonic waves are input and receives ultrasonic waves. However, such a stacked piezoelectric body requires a thick piezoelectric body, making it difficult to achieve thinning or miniaturization. [0003] In contrast, there is known an ultrasonic transducer using a thin-film piezoelectric film (for example, refer to Patent Document 1) composed of a vib...
