Colibrys Launches Worlds Best Open-Loop MEMS Accelerometer Displacing Traditional High Cost, Fragile Solutions

Neuchatel, Switzerland (PressExposure) May 27, 2009 -- Colibrys confirm launching today the IRIS accelerometer family, world’s best open-loop MEMS accelerometer, to displace traditional vibrating quartz and electromechanical solutions. MEMS establishes a new competition to historical high-end motion sensors, as typically offered by Honeywell, by pushing the boundaries of its performances, offering higher robustness at reduced cost in safety critical and harsh environment applications.

The first product released based on IRIS technology is RS9010.A. This ±10g sensor specifically designed for AHRS (Attitude Heading and Reference Systems) and mid accuracy navigation application offers an order of magnitude improvement over existing leading MEMS technology and now seriously compete with traditional vibrating quartz and electromechanical solutions. This product uses an open loop electronic interface, specifically designed for long term stability. The enhanced sensor design provides an overall composite repeatability of bias better than 1.5mg (1σ) for ±10g and a scale factor repeatability of 500ppm (1σ). The vibration rectification coefficient is 150μg/g².

“RS9010 will enable the AHRS designers to obtain excellent performance at reduced cost while benefitting from the inherently rugged MEMS sensor, which open new application opportunities and simplifies sensor handling during the manufacturing process” commented Soheil Habibi, Business Development Manager for Colibrys inertial sensors.

He added further “IRIS is a big step forward in realizing our vision to commercializing μg stability accelerometers with high shock resistance and high operating temperature, displacing the established vibrating quartz and electromechanical solutions. We believe that in near future, we will have μg stability accelerometers and high stability gyros based on MEMS technology, enabling a wide range of existing and new applications in the Defense and Aerospace markets”.

About MEMS Technology MEMS (Micro-Electrical-Mechanical Systems) are highly miniaturized devices that can realize a number of physical sensing functions including fluidics, optics and mechanics on a silicon chip using techniques similar to traditional integrated circuit process technology. MST (Microsystems) merge these sensing and or actuating functions combining them with electronic signal process chips to create highly miniaturized systems that enable enhanced levels of perception, control and performance.
