초록
A new method was developed to fabricate 1-3 piezo composite, a part of ultrasonic transducer. PZT rod arrays were made by pressing PZT green sheet with LIGA mold, and were sintered. Its dielectric constant and electro-mechanical coupling coefficient showed 4000 and 55% at 1kHz, respectively. So, PZT rod arrays made by means of this process can be applied to ultrasonic transducer.
