Got a question? We get those a lot. So we've compiled some of them here to help out. If you still can't find the answer you're looking for, get in touch with us and we'll be happy to help.

How do MEMS pressure sensors work?

MEMS pressure sensors make use of piezoelectricity. Pressure applied to certain materials produces an electrical voltage, which can be measured. MEMS piezo-resistive sensors sense a change in resistance across a thin silicon diaphragm. This technology is widely used in industrial sensors and is well proven. The sensors are rugged and measure pressure only at the source. Over the years, Millar has perfected integration methods with these sensors to greatly reduce the effects of drift resulting from integration. Catheters built with sensor tips are robust and can navigate tortuous paths in the human vasculature. The interface electronics are fairly simple and can connect to commercially available monitors. Since pressure is measured only at the tip, this technology does not suffer from damping and resonance effects of fluid-filled lines.

What size sensors do you integrate?

We offer a diverse range of sensor sizes for integration, catering to various medical applications. Our sensors span in size from 1F (French) to 3F (French), accommodating a wide spectrum of medical device requirements.

The integration process of these sensors is a meticulous and collaborative endeavor. Our comprehensive approach involves several steps, including assessment, consultation, sensor selection and more. To learn more about the integration process and how Millar can assist you, contact us today.

What is the average lifespan of a sensor that you integrate?

The average lifespan of a sensor that we integrate can vary based on its application and usage. Our sensors are designed to function in both short-term and long-term applications, with operational lifespans ranging from less than 24 hours to greater than 5 years.
