Piezoelectricity and Ultrasonics technologies Laboratory - PULETS - belongs to mechanical engineering department of École de Technologie Supérieure - ÉTS - based in Montreal, Canada. It aims to develop innovative ultrasonics non destructive testing technolgoies as well as the study of innovative materials and their failure analysis. To meet those goals, the laboratory works in a interdisciplinary context, looking to make the link between mechanics, physics, electronics and materials science.
