Abstract

L'invention concerne un capteur tactile qui comprend un substrat capable de propager des ondes acoustiques. Le substrat comprend une première surface comportant une région tactile. Dans un mode de réalisation, le substrat comprend une première paroi latérale qui croise la première surface en un premier bord. Un émetteur est aménagé sur la première paroi latérale du substrat. L'émetteur produit des ondes acoustiques qui se propagent directement depuis la première paroi latérale à travers au moins une partie de la région tactile. Dans un autre mode de réalisation, un transducteur est formé sur le substrat. Le transducteur comprend un élément piézoélectrique qui est durci thermiquement après avoir été formé sur le substrat. Le transducteur est configuré pour produire et/ou détecter des ondes acoustiques. Dans encore un autre mode de réalisation, le transducteur peut comprendre une barrette comprenant l'élément piézoélectrique.
