Abstract
A sensor (10) includes a plurality of sensing elements (14-20) deposed on a sensor substrate (12) and an electronic switching circuit (22) electrically connected to each of the sensing elements (14-20) for electrically selecting at least one of the sensing elements (14-20).
Claims11
A sensor comprising:
- a sensor substrate;
- a plurality of sensing elements deposed on the sensor substrate wherein each sensing element has at least one output signal, and
- an electronic switching circuit electrically connected to each of the sensing elements for electronically selecting at least one of the sensing elements wherein the electronic switch circuit includes a means for measuring the output signal to select the at least one of the sensing elements having a measured output signal corresponding to a desired output signal.
A sensor comprising:
- a sensor substrate having opposed top and bottom surfaces and presenting structure defining a cavity having an outer edge at the bottom surface and forming a diaphragm;
- a plurality of sensing elements deposed on the top surface at varying distances from the outer edge and over the diaphragm, wherein each sensing element has at least one output signal;
- and
- an electronic switching circuit electrically connected to each of the sensing elements for electronically selecting at least one of the sensing elements wherein the electronic switch circuit includes a means for measuring the output signal to select the at least one of the sensing elements having a measured output signal corresponding to a desired output signal.
