Patent

CA 2501972

A method and apparatus for non-invasive measurement of living body information comprises a light source configured to generate light containing a specific wavelength component, an irradiation unit configured to irradiate a subject with the light, and at least one acoustic signal detection unit including piezoelectric devices formed of a piezoelectric single crystal containing lead titanate and configured to detect an acoustic signal which is generated due to the energy of the irradiation light absorbed by a specific substance present in or on a subject.

L'invention concerne un procédé et un appareil de mesure non invasive de données d'un organisme vivant. Cet appareil comprend une source lumineuse permettant de générer une lumière et comprenant un composant de longueur d'onde spécifique, une unité de rayonnement permettant d'exposer un sujet à la lumière, et au moins une unité de détection de signaux acoustiques comportant des dispositifs piézo-électriques constitués d'un unique cristal piézo-électrique contenant du titanate de plomb et permettant de détecter un signal acoustique qui est généré grâce à l'énergie des rayons lumineux absorbée par une substance spécifique présente dans ou sur un sujet.
