OMRON has declared that it will launch an absolute pressure sensor in January 2013. This sensor can precisely detect 50 cm altitudinal variations by accurately sensing air pressure fluctuation.
Based on the latest MEMS technology, Omron has developed an absolute pressure meter that ensures power and precision efficiency, regardless of its subminiature dimensions.
Omron integrated CMOS circuits and MEMS sensors to create an absolute pressure sensor that measures 3.83.8×0.92 mm leading to easy and simple installation in small-sized mobile devices as well as in compact hardware. With high power efficiency, the sensor can be used ideally in battery-operated applications including activity monitors and smartphones. Pressure sensors, installed within activity monitors, will consider the altitudinal variation in a day’s routine activities and exercises like climbing hills or up and down stairs. When these sensors are incorporated in car navigation systems, high precision navigation guidance can be achieved within multistory car parks, and also enabling these systems to differentiate elevated roadways from the ground-level roads lying underneath. The sensors can b ideally used for building security applications for air pressure variation detection.
In addition, Omron intends launching the integrated CMOS-MEMS wafers for enabling installation of other sensors on the same board resembling the absolute pressure sensor.
At the Micromachine/MEMS ROBOTECH 2012 exhibition taking place at Tokyo Big Sight, Omron will showcase its new MEMS absolute pressure sensor from July 11 to July 13.
