Silicon Microstructures strengthens its Position in the Medical MEMS Market

Market Wire, January, 2008

Silicon Microstructures, Inc. ( www.si-micro.com ), a leader in MEMS silicon sensor design and manufacture and a subsidiary of ELMOS, today announced that the company has been selected by OMRON Healthcare, Inc. as a development partner and supplier for an advanced pressure sensor array for pulse wave transient blood pressure measurement - the so called radial Augmentation Index.

The radial Augmentation Index measurement method provides a novel and highly accurate approach for non-invasive diagnosis, screening, and monitoring of the arterial condition, especially arterial stiffness, arterial impedance mismatch, and cardiac afterload.

SMI's experience with ultra-miniature pressure sensors for the medical and automotive market, together with its superior design capabilities and technology expertise for advanced pressure sensing solutions has qualified SMI as the supplier of choice for OMRON Healthcare, Inc.

"The selection of SMI as a supplier for this advanced technology project by OMRON Healthcare, Inc. is another strategic milestone for SMI" said Rainer Cholewa, President and CEO of SMI. "We have the required level of expertise and the right technology portfolio in order to address high-end medical sensor applications, and this design win underlines our strong positioning in this market."

The array sensor for OMRON Healthcare, Inc. is another addition to SMI's medical product portfolio, which already includes an ultra-miniature disposable catheter tip pressure sensor for blood pressure measurement inside the coronary arteries of the human heart, and a range of differential low-pressure sensor products for anesthesia equipment and respiratory applications, like sleep apnea therapy.
