摘要：
In this work we report some electroacoustic characteristics of miniature piezoelectric ultrasound transducers, manufactured by screen printing and using thick film technology. To make transducer samples, ink with PZT powder and a glass frit was employed. PZT films of 100-130 mum thick were screen-printed between two gold electrodes over alurnina. Electrical impedance and acoustic emission continuous-wave analysis at 1-10 MHz range shows two main vibrating modes, one of PZT layer itself and other with substrate and PZT vibrating as a whole and coupling characteristics of a two elements set and an array.
