PROCEDE DE FABRICATION D'UNE SONDE ACOUSTIQUE MULTIELEMENTS UTILISANT UN FILM POLYMERE METALLISE ET ABLATE COMME PLAN DE MASSE |
摘要 |
<p>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.</p> |
