Title
(EN) IMPLANTABLE MICROSCALE PRESSURE SENSOR SYSTEM
(FR) MANOMETRE MINIATURE IMPLANTABLE
Abstract
(EN)
A MEMS chip sensor (10, 20, 30, 40, 50, 60, 70) based upon detection of an induced inductance in the sensor is described. The sensor is used in an environment for detection of fluid pressures The method and system is particularly used in animals, including humans, to sense pressure changes, particularly pressure in the eyeball.
(FR)
L'invention porte sur un détecteur de pression sur puce MEMS (10, 20, 30, 40, 50, 60, 70) se basant sur la détection d'une inductance induite dans le détecteur, et s'utilisant dans un environnement de détection de pressions de fluides, particulièrement chez l'animal et chez l'homme, pour mesurer des variations de pression notamment dans le globe oculaire.
