Following its toughest year in recent memory, the market for Microelectromechanical System (MEMS) automotive sensors will rebound sharply in 2010, but continued high sales might lead to an overheated market that could push the industry back into depression, according to new research from iSuppli Corp. Global shipments of automotive MEMS sensors are projected to reach 591.2 million units in 2010, up a resounding 17.8 percent from 502.0 million. Such growth represents a welcome turnaround after a challenging 2009 for MEMS sensors. While early 2009 saw orders to sensor companies all but dry up because of the fallout of the economic recession, shipments picked up rapidly in the fourth quarter, exceeding even the high point reached in 2007. However, the newly strengthened market in 2010 marks the beginning of an upturn that will continue until at least the end of 2014, iSuppli data indicate.
