We will present our new market forecast 2010-2016 for MEMS inertial sensors. The consumer and automotive inertial sensors market saw a healthy 15% growth in 2011 to surpass a $2.7 billion business, thanks to the increasing penetration of more motion sensing into more mobile devices and more automotive safety systems in more cars across the globe. The market and technology trends will be detailed. We will focus on the development of sensor combos. The key drivers to integrate several MEMS sensors in a package are to provide cost / size decrease, or to provide new functionalities with sensor fusion. We will see that sensor fusion with specific software brings a lot of the value, because MEMS players are now trying to sell functions rather than sensors. Lastly we will focus on describing the leading players and the hot developments in this area. The development of MEMS combos implies new business models which are shaking the MEMS industry. The complexity of the inertial MEMS supply chain and the major evolutions will be highlighted in this presentation.
