MEMS stands for “MicroElectroMechanical System”. “Micro” means these devices measure less than a millimeter in any direction. They are “systems” in that they employ both electrical and mechanical forces in a single unit.
Millar pressure transducers are the “gold standard” for accurate measurement of pressure in humans and research animals. Throughout Millar’s history, the company has developed progressively smaller sensors both to minimize interference with physiological parameters and to access smaller venues. Miniaturization to the level of MEMS devices opens up new opportunities for acquisition of pressure information in greater detail and from formerly inaccessible areas.
MEMS pressure sensors make use of piezoelectricity. Pressure applied to certain materials produces an electrical voltage, which can be measured.
