Abstract:
A micro pressure sensor includes a body having a compartmentalized chamber provided by membranes anchored between opposing walls of the body and carrying electrodes disposed on surfaces of the membranes. The body has a first pair of opposing walls and a second pair of opposing walls orthogonal to the first pair that define a chamber, a plurality of membranes having a correspond electrode layer over a surface, the plurality of membranes disposed in the chamber, anchored between the first pair of opposing walls of the body to provide plural compartments, a first set of ports coupled to a first set of the plural compartments, the first set of ports disposed in corresponding portions of a first one of the first pair of opposing walls of the body, with a second one of the first pair of opposing walls of the body being a solid portion of the body; and a second set of ports coupled to a second different set of the plural compartments, the second set of ports disposed in corresponding portions of the second one of the first pair of opposing walls of the body, with the first one of the first pair of walls of the body being a solid portion of the body.
