PZT-EPOXY계 초음파프루브 제작과 특성에 관한 연구
A Study on the Development and Characteristics of PZT-EPOXY Ultrasonic Probe
초록
The electrical properties of the ultrasonic probes and the piezoelectric composite materials with 1-3 connectivity by the extrusion method have been studied. The relative permittivity and piezoelectric coefficient increase linearly as PZT volume% increases and resonance frequency moves to low frequency as the sample thickness increases. The acoustic impedance matching with body and water is better than PZT ceramics' and the reception sensitivity is fine as the thickness thins down.
