Ultrasound array transducer manufacturing

A method for manufacturing, or for use in manufacturing, a flexible ultrasonic transducer for imaging and non-destructive testing, the method comprising:

• providing a layer of piezoelectric material on a metallic foil substrate;
• using additive techniques to apply a plurality of electrodes to a surface of the piezoelectric material and to apply a plurality of electrical conduction tracks and a plurality of electrical connectors to a surface of a layer of dielectric material provided on the surface of the piezoelectric material, wherein the electrodes are arranged in an electrode array, and respective electrical conduction tracks of the plurality of electrical conduction tracks electrically connect a respective electrode of the plurality of electrodes to a respective electrical connector;
• wherein the additive techniques comprise at least one of:
• masking, deposition, photo patterning, printing or patterned coating, and the respective electrode is integrally formed with the respective electrical conduction track and the respective electrical connector using the additive techniques.
