How (MEMS) Oil-filled-pressure-sensor WorkIn MEMS sensor technology, the pressure of the media is measured by a silicon or silicon-on-insulator sensing element that has the piezoresistive strain gage bridge on it, with a transfer medium, typically silicon oil, present between the MEMS element and a stainless-steel diaphragm.

Thin Film Sensors and TransducersDuring the manufacturing process, a mechanism is built upon the backside of the transducer’s sensing diaphragm. Through a sputtering process, a small circuit is created that contains on it a Wheatstone-bridge resistance network. As pressure is applied to the diaphrag

With the rise in smart watches and navigation systems, absolute pressure sensors find homes wherever elevation above sea level (altimeter measurement) is required. Weather stations also use them for barometric pressure measurements.
