SMI launches new SM1120 catheter mountable pressure sensor for the 1-French catheter market. With an industry-leading in vivo stability, design engineers will appreciate the high level of performance, miniature size, and quality.

SM1120 Catheter-Mountable Pressure Sensor

“The SM1120 provides manufacturing flexibility by providing various wirebond pad options.”

SMI (Silicon Microstructures, Inc.), a global MEMS pressure sensor company, today announced it has launched the SM1120 MEMS based ultra-miniature pressure sensor designed especially for the 1-French catheter market. The microsensor profile at only 220um x 75um provides ample space for 1-French catheter designs, enabling maneuverability to reach challenging locations. With industry leading in vivo drift performance of 2 mmHg per hour, the SM1120 provides a broad operating pressure range from 0 to 1,100 mmHg absolute. Pad options include gold, platinum and solder bumped for design and manufacturing flexibility.

At the heart of the SM1120 is the MEMS pressure transducer with SMI’s novel and proprietary silicon technology platform. With SMI’s technology, the user can attain the highest level of accuracy as demanded of the stringent medical industry. Design engineers will appreciate the design flexibility and repeatability of the SM1120. Samples are readily available for design-in and user evaluation.
