MEMS Processes Help Make More Precise and Economical Pressure Sensors

Micro-Machined silicon reduces the lead times needed to manufacture custom pressure sensors.

Several different transduction methods can be used to convert pressure to a practical, measurable electrical  signal. Most modern devices depend on the change in resistance of a  metal foil or a semiconductor under a load. A signal-conditioning circuit converts the resistance change to a  proportional electrical  output signal. A Wheatstone bridge is the most common type of
