MEMS Pressure Sensor Integration
Sensor Selection
Millar's proven MEMS pressure sensor integration process starts with sensor selection, which is based on application, size, characteristics, length of use, accuracy and drift requirements. Our OEM Solutions team understands the nuances of each sensor and how to achieve the best results.
Optimized MEMS Pressure Sensor Integration
Millar's optimized integration process, developed over more than 50 years of continuous innovation, is guaranteed to improve yields and circumvent MEMS integration challenges, resulting in reduced cost and rapid time to market for integrated medical devices.
Applications Using MEMS Pressure Sensors
Viable applications for MEMS pressure sensor integration are virtually limitless, including cardiovascular, airway pressure, intracranial pressure, compartment pressure, spinal pressure and urodynamics.
What is MEMS Technology?
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.
Why use MEMS for medical devices?
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 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
Codman Microsensor® ICP Transducer Revolutionizes TBI Treatment
Codman, now part of Integra LifeSciences, reached out to Millar OEM Solutions in 1990 to develop a better method for measuring intracranial pressure (ICP) in patients with traumatic brain injury (TBI). Millar's patented strain-gauge technology in the Codman Microsensor® ICP Transducer gives medical practitioners the precise, reliable information they need to intervene quickly and relieve brain-damaging pressure. To date, Millar has manufactured more than 1.1M units for Codman that have revolutionized TBI treatment. Download our case study to learn more.
