摘要： A flexible ultrasonic transducer comprising a flexible metal plate, a piezoelectric ceramics element attached on the plate, a first electrical conductor such as a conductive wire which is electrically conductive attached to the plate and an insulation covering which covers at least a portion of the metal plate, wherein the metal plate comprises a first outer surface and a second outer surface lying opposite to each other wherein the piezoelectric ceramics element is attached to the first outer surface wherein the dimensions of the first outer surface and the piezoelectric ceramics element are such that a first portion of the first outer surface is not covered with the piezoelectric ceramics element wherein the first electrical conductor is electrically conductive attached to at least one of a first portion of the second outer surface and the first portion of the first outer surface wherein the first portion of the first outer surface and the first portion of the second outer surface lie opposite each other and have about the same dimensions and positions in a plane wherein the metal plate extends and wherein at least a portion of the insulation covering covers the first portion of the first outer surface so that the piezoelectric ceramics element is arranged to be directly dry coupled to an surface of an object to be inspected by means of the transducer.
