Other MEMS pressure sensors. There are other ways of making MEMS pressure sensors that can be used. For example, a mechanical structure can be created with a resonant frequency that is a function of applied pressure (like tuning a piano string). A signal is applied to cause the structure to vibrate and the change in resonant frequency is measured.

Jul 29, 2020· For direct measurement, a MEMS pressure sensor checks the inflation of each tire. In an indirect system, magnetic wheel speed sensors identify a wheel rotating faster than anticipated – an underinflated tire is a “smaller” tire and will have to rotate more often to keep pace with a properly inflated tire.
