[[Piezoresistive pressure sensor]]s use the variation of resistivity of silicon with stress. A piezoresistive sensor consists of a silicon diaphragm on which silicon resistors are diffused during the manufacturing process. The diaphragm is bonded to a silicon wafer. The signal must be corrected for temperature variations.<ref name="omega" >{{cite web|url=https://www.omega.com/en-us/resources/types-pressure-sensor |title=Pressure sensor |date=17 April 2019 |website=www.omega.com |access-date=9 December 2019 }}</ref> These pressure sensors are commonly used in [[dive computer]]s.<ref name="amsys" >{{cite web|url=https://www.amsys.info/sheets/amsys.en.wp02.pdf |title=How to measure absolute pressure using piezoresistive sensing elements |website=www.amsys.info |access-date=9 December 2019 }}</ref>
