A sensor includes a substrate, an electrode, a deformable membrane, and a compensating structure. The substrate includes a first side and a second side. The first side is opposite to the second side. The substrate comprises a cavity on the first side. The electrode is positioned at a bottom of the cavity on the first side of the substrate. The deformable membrane is positioned on the first side of the substrate. The deformable membrane encloses the cavity and deforms responsive to external stimuli. The compensation structure is connected to outer periphery of the deformable membrane. The compensation structure creates a bending force that is opposite to a bending force of the deformable membrane responsive to temperature changes and thermal coefficient mismatch.
