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.
