Article: Reports outline ultrasonic research study results from University of California, National Institutes of Health.

According to a study from the United States, "This paper presents the design, fabrication, and measurements of very high frequency kerfless linear arrays prepared from PZT film and PZT bulk material. A 12-mu m PZT thick film fabricated from PZT-5H powder/solution composite and a piece of 15-mu m PZT-5H sheet were used to fabricate 32-element kerfless high-frequency linear arrays with photolithography."

"The PZT thick film was prepared by spin-coating of PZT sol-gel composite solution. The thin PZT-5H sheet sample was prepared by lapping a PZT-5H ceramic with a precision lapping machine. The measured results of the 2 arrays were compared. The PZT film array had a ...
