Ce travail porte sur la réalisation de capteurs interdigités (IDT pour InterDigital Transducer) sur des supports piézoélectriques. L’enjeu est double puisqu’il s’agit premièrement de disposer de capteurs efficaces pour générer des ondes de surface acoustiques (SAW pour Surface Acoustic Wave) afin de caractériser la qualité des revêtements et des surfaces de structures. Le deuxième objectif de cette étude est de rendre ces capteurs IDT flexibles afin qu’ils puissent s’adapter non seulement aux différentes géométries planes ou non mais aussi pour qu’ils soient capables de supporter les déformations des structures au cours de leur utilisation. En général, les matériaux piézoélectriques sont rigides et le caractère souple des matériaux est souv...
