Abstract

La présente invention concerne un détecteur d'information biologique, un procédé de détection d'information biologique, et un terminal mobile pourvu du détecteur d'information biologique. Le détecteur d'information biologique, le procédé de détection d'information biologique, et le terminal mobile sont capables de prévenir une hausse dans la taille et le coût du détecteur d'information biologique et du terminal mobile et de détecter une information biologique avec une bonne précision. Le détecteur d'information biologique (1) comprend un circuit d'oscillation (2), une électrode d'application (3), une électrode de détection (4), un circuit de mesure de la capacité électrique (5), et un circuit de calcul (6). Le circuit d'oscillation (2) génère des impulsions électriques. Les impulsions électriques sont appliquées à l'électrode d'application (3). L'électrode de détection (4) fait face à l'électrode d'application (3). Le circuit de mesure de la capacité électrique (5) mesure une capacité électrique entre les électrodes. Le circuit de calcul (6) permet d'obtenir une information biologique en se basant sur une différence entre une capacité électrique dans un premier état et une capacité électrique dans un second état.
