Abstract

Selon différents modes de réalisation, l'invention concerne un procédé de détermination de l'élasticité cutanée. Le procédé peut, pour au moins une zone cutanée d'un utilisateur, comprendre les étapes suivantes : - déformation de la peau à l'aide d'un dispositif de mesure de l'élasticité cutanée, le dispositif de mesure de l'élasticité cutanée pouvant faire partie d'un dispositif portable, - détection d'un signal fonction de l'élasticité cutanée fourni pendant une déformation de la peau et - affectation d'une élasticité cutanée au signal détecté par comparaison du signal détecté avec des signaux de référence d'élasticités cutanées connues.
