ABSTRACT:
This invention relates to a novel design of a microprobe for measuring intensity distribution, instantaneous intensity values and acoustic signal shapes of ultrasound. The probe consists of a rod-shaped electrode which is fixed with the aid of an electrically and acoustically insulating material in a sleeve-shaped electrical shield. To one end surface of said device is adhered a piezoelectric film such that the film will come in contact with the end surfaces of the electrode, the insulating material and the electrical shield. As only the outer surface of the piezoelectric film is covered by an electrically conductive layer, the rod-shaped electrode on the inner side of the film will determine the active surface of the probe.
