DEF

Capteur qui génère un signal électrique variant en fonction de la pression exercée sur le matériau piézoélectrique qu'il contient, en l'occurrence de la céramique polarisée, et qui permet ainsi la détection d'objets, la mesure de grandeurs physiques ou la reproduction de phénomènes.

CONT

Par ailleurs, un capteur piézo-céramique enregistrant les vibrations crâniennes permet de distinguer les cris de l'animal en expérience de ceux des autres animaux du groupe, en comparant les signaux provenant du microphone ambiant et ceux du capteur crânien de vibrations [...]
