Abstract

La présente invention se rapporte à un revêtement piézosensible (12) pour la détection d'impacts (121, 122, 123, 124) sur un substrat (10), comprenant une matrice dans laquelle est dispersé au moins un pigment piézochrome, ladite matrice est une matrice polymérique, le pigment piézochrome est choisi de façon à ce que ledit revêtement change de couleur à partir d'un seuil de pression déterminé, correspondant à une pression, soit de transition dudit pigment piézochrome dans ladite matrice entre deux formes polymorphiques de couleurs différentes, soit de transition de spin dudit pigment dans ladite matrice. L'invention se rapporte également à un procédé de réalisation d'un tel revêtement piézosensible.
