Développement de bases de données de publications en matériaux intelligents

Ces bases de données, construites pour différents matériaux intelligents comprennent une liste des auteurs, le titre, les détails de la publication, les mots clés, et toutes autres informations d’intérêt général. Ces bases de données sont disponibles en ligne mais avec accès contrôlé.
La base de données piézoélectriques
La plus vaste des base de données avec 9815 entrées. Elle est basée sur la caractérisation et les propriétés des matériaux piézoélectriques. Une recherche en ligne s’effectue à partir des différents champs de données, soient l’auteur, le titre, une autre information ou le numéro de référence. Ce numéro de référence est unique et sert à identifier l’article et à gérer les données.
La base de données electret et piézoélectrique polymère
La plus petite avec 208 entrées. Ce domaine est très en demande et devrait se développer très rapidement.
La base de données de fluides magnétorhéologique & éléctrorhéologique
Contient des références spécifiques à ces fluides qui changent de propriétés d’une façon notable sous l’action de champ magnétique ou électrique. L’utilisation de ces fluides dans les amortisseurs, les freins, les embrayages est fréquente dans les secteurs automobile et électronique. À ce jour, la base de données magnétorhéologique contient 437 entrées tandis que celle électrorhéologique contient 691 entrées.
La base de données de l’Alliage à mémoire de forme
Elle a passé de 300 entrées en 2005 à plus de 1500 en 2008.
