LOW COST SILICON CORIOLIS' GYROSCOPE PAVES THE WAY TO CONSUMER IMU

摘要

During the last two years MEMS linear accelerometers have reinvented the way of playing a game, protecting your sensitive data on HDD, using your mobile devices smartly or making your washing machine less power hungry. Consumer and Industrial Markets have taken advantage from "The MEMS Consumerization Wave", driven by STMicroelectronics, which introduced a wide portfolio of two and three-axis motion sensors meeting customer requirements in terms of size, performances, quality and price.rnWhat's next? More and more applications in the Consumer and Industrial markets are coming up with the need of sensing motion along multiple axes degree of freedom. Linear motion detection is requested to be combined with angular rate sensing along pitch, yaw and roll axis in the space to address a wide range of applications where four to six degree of freedom sensing feature is required. One example is related to Inertial Measurement Unit (IMU) or Inertial Navigation Unit (INU) where accelerometer and gyroscopes are each other complementary to detect linear and angular motion in several applications including image stabilization, enhanced user interface for mobile phones, games and pointers/ remote controllers, pedestrian and car navigation for location based services and fitness/wellness people monitoring. As seen for the accelerometer, once again size, performances and price are the driving factors for gyroscope success in Consumer & Industrial market.
