Abstract

The paper describes the design, fabrication, and measurements of a high-frequency ultrasound kerfless linear array prepared from hydrothermal lead zirconate titanate (PZT) thick film. The 15-¿m hydrothermal PZT thick film with an area of 1 × 1 cm, obtained through a self-separation process from Ti substrate, was used to fabricate a 32-element 100-MHz kerfless linear array with photolithography. The bandwidth at ¿6 dB without matching layer, insertion loss around center frequency, and crosstalk between adjacent elements were measured to be 39%, ¿30 dB, and ¿15 dB, respectively.
