  • Fluid sensor with mechanical positional feedback
    Patent number: 7921726
    Abstract: A fluid detection device is herein disclosed as including a sensor mount, a flexible deflection sensor rigidly connected to the sensor mount and a stiffener. The stiffener is arranged together with the flexible deflection sensor such that the flexible deflection sensor is preconfigured to deform in a predetermined manner when the fluid detection device is exposed to a fluid. An amount of the deformation of the flexible deflection sensor determines a property of the fluid. A pressure sensing apparatus is herein disclosed as including a rigid perimeter, a flexible membrane forming a surface area bounded by the perimeter, and a sensing means in communication with the flexible membrane. The flexible membrane is configured to elastically deform when a pressure force is exerted on the surface area, and the sensing means is configured to measure an amount of deformation of the flexible membrane.
