Microelectromechanical systems (MEMS) sensor applications continued warming, especially in the iPad advent of smart phones to expand coverage, as well as three games Depot efforts to promote movement sensing products driven by penetration is bound to steadily increased . According to research agency iSuppli pointed out that, despite the recession in 2009, MEMS sensors in cell phones and consumer electronics sales continue growth trend of 7.6%, from 1.1 billion in 2008 increased from 1.1 billion in 2009, 9,000 million dollar.
