Abstract

A pressure sensor that is implantable within a living being that wirelessly provides pressure data within the living being to a wireless receiver. The pressure sensor includes an elastic membrane to which at least one capacitive actuator is coupled for applying a known force to the membrane to determine membrane characteristics. The pressure sensor includes a force transducer contacting the membrane for determining the pressure within the living being and which includes an internal calibrating force mechanism. This calibrating force mechanism permits force transducer displacement away from the membrane where a zero force transducer reading is taken and then applying a calibrating force and taking another reading. From these two points, a force transducer characteristic is derived and, along with membrane characteristics, an accurate pressure within the living being is obtained from the sensor. An alternative embodiment replaces the capacitive actuators with a known mass and an external vibratory source.
