Abstract

Il procedimento prevede l'estrusione di una struttura tubolare multistrato, con strato più interno semiconduttivo. Nella realizzazione del manicotto, tale strato interno viene parzialmente asportato, lasciandone solo una porzione centrale che forma un elettrodo. Inoltre, lo strato intermedio è realizzato con una particolare mescola, così da avere costante dielettrica relativa e rigidità dielettrica prefissate.
