Ultrasound Transducer Manufactured by Using Micromachining Process, its Device, Endoscopic Ultrasound Diagnosis System Thereof, and Method for Controlling the Same |
摘要 |
An ultrasound transducer manufactured by using a micromachining process comprises: a first electrode into which a control signal for transmitting ultrasound is input; a substrate on which the first electrode is formed; a second electrode that is a ground electrode facing the first electrode with a prescribed space between the first and second electrodes; a membrane on which the second electrode is formed and which vibrates and generates the ultrasound when a voltage is applied between the first and second electrodes; a piezoelectric film contacting the membrane; and a third electrode electrically continuous to the piezoelectric film.
