Porous PZT substrate

The thick films on the porous PZT substrate appear to be a good solution for transducer fabrication due to a relatively high attenuation that limits the required backing thickness and high acoustical impedance, very close to the thick-film acoustical impedance, which increases the transducer bandwidth. The high value of thickness coupling factor allows a high transducer sensitivity to be obtained. The almost identical chemical composition of the thick film and substrate minimise chemical and physical interactions during processing of active PZT layer on the substrate.
