Title:
マルチセル・トランスデューサー
Document Type and Number:
Japanese Patent JP6693941
Kind Code:
B2
Abstract:
The present invention relates to a transducer device having a planar array of electroacoustic cells, each including a piezoelectric bilayer unit. The transducer device achieves high transmission sensitivity across a broad bandwidth. The transducer device may be designed to have a broad or a focused directivity pattern, or may be multifrequency, depending on the particular application and has a range of applications. For example, the transducer device may be used with an implanted passive ultrasonically excitable resonating sensor, to excite the sensor and/or to interrogate the sensor, for example in conjunction with Doppler-based analysis of the resonance frequency of the sensor, and/or to locate an implanted sensor. The invention also relates to a method of manufacturing the device.
