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.

Case Study
OEM Solutions Partner Revolutionizes TBI Treatment

A medical device manufacturer reached out to Millar OEM Solutions in 1990 to develop a better method for measuring intracranial pressure in patients with traumatic brain injury (TBI). Since then, we have manufactured nearly one million patented strain-gauge pressure sensors that have revolutionized TBI treatment.
