Beschreibung
Zusammenfassung:	In a particular embodiment, a pressure sensor apparatus for strain gauge pressure sensing is disclosed that includes a plurality of strain gauges comprising a first strain gauge and a second strain gauge. The pressure sensor apparatus also includes a diaphragm coupled between the plurality of strain gauges and an object configured to apply pressure to the diaphragm. The diaphragm has a first portion and a second portion. The first portion has a first thickness between the object and the first strain gauge. The second portion has a second thickness between the object and the second strain gauge. In an uncompressed state, the second thickness is greater than the first thickness.
