Method for making a multielement acoustic probe using a metallised and ablated polymer as ground plane

摘要

The invention concerns a method to manufacture acoustic probes comprising unitary piezoelectric transducers. The method comprises an original step to realize an earth plane formed from a flexible dielectric film covered by a conducting film. The flexible dielectric film is ablated locally to expose the conducting film. The ablated film acts as draping and earth plane for the unitary piezoelectric transducers.
