Abstract
Techniques are described herein that perform capacitance-based pressure sensing using pressure vessel(s). A pressure vessel is an object that has a cross section that defines a void. The void has a shape that is configured to change based on a change of pressure difference between a cavity pressure in a cavity in which at least a portion of the pressure vessel is suspended and a vessel pressure in the pressure vessel. The pressure vessel may be formed in the shape of an enclosed loop (e.g., along a path that is perpendicular to the cross section), resulting in a looped pressure vessel. For instance, an end of the pressure vessel may be connected to another end of the pressure vessel to form the enclosed loop.
