Abstract

L'invention concerne un dispositif de mesure 10 qui mesure des informations biologiques en ayant une zone à examiner en contact avec une unité de contact 14 et qui est pourvu : d'une unité de détection de pression 31 qui détecte une pression appliquée à l'unité de contact 14 ; d'une source de lumière laser 21 qui émet une lumière laser ; d'une unité de réception de lumière 22 qui reçoit la lumière diffusée de la lumière laser, ladite lumière diffusée ayant été diffusée depuis la zone à examiner ; d'une unité de commande de capteur 35 qui commande l'alimentation en énergie vers l'unité de détection de pression 31, la source de lumière laser 21 et l'unité de réception de lumière 22 ; d'une unité de génération d'informations biologiques 18 qui génère les informations biologiques sur la base de la sortie de l'unité de réception de lumière 22. L'unité de commande de capteur 35 exécute une commande de telle sorte que de l'énergie est fournie à la source de lumière laser 21 et à l'unité de réception de lumière 22 dans un état dans lequel la pression détectée par l'unité de détection de pression 31 est dans une plage de pression prédéterminée.
