ULTRASONIC PROBE

摘要

PURPOSE:To provide an ultrasonic probe with excellent characteristics by imbedding a number of needle shaped crystal of antimony sulfaiodide in a sheet shaped organic material to form a composite piezoelectrc material. CONSTITUTION:The needle shape crystal of antimony sulfaiodide is produced by the vapor growth method. A number of the needle shaped crystal 12 is imbedded in the sheet shaped organic material 11 to form the composite piezoelectric material. The composite piezoelectric material thus produced facilitates the manufacture of uniform one, and has better piezoelectric characteristics than one made of PZT ceramic fiber. Therefore, this type of composite piezoelectric material provides the ultrasonic probe with excellent characteristics.
