MEMS Sensors Advance Medical Device Development

MEMS pressure sensors operate by converting pressure signals into electrical signals via small strain gauges, called piezoresistors, implanted in a thin silicon membrane. As pressure deflects the membrane, it creates mechanical strain, which is then transformed into a change in electrical resistance and read out as a change in voltage. The interface electronics can connect to commercially available monitors and leverage existing device circuitry, reducing system complexity, lowering project costs, and increasing speed to market.
