Micro Electro Mechanical Systems on the rise
MEMS sensor/actuator growth rate to double in next five years
New applications in consumer and portable systems accelerate sales, says new report. New motion control user interfaces on consumer electronics and drop detection/protection features in portable systems are helping to accelerate the growth of semiconductor devices built with micro electromechanical systems (MEMS) technology. Worldwide sales of MEMS based semiconductor sensors and actuators are now expected to increase at a compound annual growth rate (CAGR) of 19% between 2007 and 2012, reaching $9.7 billion in five years compared to $4.1 billion in 2007, according to IC Insights’ new 2008 Optoelectronics, Sensors, and Discretes (O-SD) Report.
The forecast growth rate is a significant increase from the 9% CAGR between 2003 and 2007. The 2008 O-S-D Report shows that 80% of today’s $5 billion semiconductor sensor/actuator market is served by devices built with MEMS technology. In these devices, tiny MEMS structures perform transducer functions for taking measurements or initiating physical actions. Among these devices are pressure sensors, accelerometers, gyroscope chips, solid state microphones, silicon MEMS oscillators, and a broad range of actuators, such as inkjet nozzles, micro mirror display devices, biochips, and radiofrequency (RF) filters, including surface acoustic wave (SAW) components.
Until recently, MEMS based devices, such as accelerometers and pressure sensors, have been heavily
dependent upon the automotive market for growth, but new, high volume applications in consumer
products, cell phones, and other portable systems have significantly increased the potential for sales
worldwide. For instance, a growing number of video game controllers are using low cost accelerometers
and gyroscope devices to operate virtual reality software instead of traditional joysticks and buttons. In
multimedia cell phones and digital music players, ‘shake control’ is made possible with new
accelerometers that integrate special functions for recognition of sudden movement as user inputs and
control. Accelerometers are also being used in portable systems to detect freefall and take immediate
action to protect hard disk drives from damage whenever units are dropped. IC Insights’ new report concludes that unit shipments of MEMS based sensors and actuators will rise at a CAGR of 27% between 2007 and 2012, reaching 4.3 billion devices in five years compared to 1.3 billion in 2007 (Figure 1). In this same period, total sensor/actuator unit shipments are forecast to increase at a CAGR of 23%, with 12.1 billion devices being shipped in 2012 compared to 4.3 billion in 2007. Overall, the sensor/actuator market is expected to reach $11.9 billion, counting all types of technologies.
