20世纪90年代后期以来，传感器市场只遭遇过一次下跌，即2009年，市场营收跌幅为2%。不过，2010年的复苏来得极为猛烈，整体市场暴涨53%。2012年O-S-D 报告显示，2011年的固态传感器市场增长幅度达到21%。预计2011年到2016年间，全球传感器销售额的复合年均增长率（CAGR）达18％，2016年营收将达到109亿美元。
按细分市场来看，加速计和陀螺仪器件仍是最大的细分市场，而且增长速度也是最快的。预计加速计和陀螺仪将在2011年的24亿美元基础上，以20%复合年均增长率增长至2016年的59亿美元。磁力计，包括霍尔传感器和电子罗盘芯片，则会在2011年13亿美元的基础上，以16%的复合年均增长率增长至2016年的27亿美元。压力传感器有望以15%的复合年均增长率从2011年的10亿美元增长至2016年的20亿美元。
加速度计和陀螺仪以及大多数的压力传感器都使用MEMS架构来侦测环境。2005年，基于MEMS技术的传感器占整体传感器市场营收的54%，目前这一数值约为70%。IC Insights预计，MEMS传感器在2011年到2016年间的复合年均增长率为19%。传感器其实涵盖于范围更广的半导体器件细分市场，这一市场包括如激励器，微镜，表面波滤波器，微流体芯片，喷墨喷嘴，以及基于电信号传导制动的MEMS器件等。而2011年，传感器给这一市场贡献了56%的营收，包括来自于激励器的44%。当年，激励器的营收为37亿美元。预计基于MEMS的激励器营收将以15%的复合年均增长率增长至2016年的75亿美元。
New Embedded Features WIll More Than Double Sensor Sales by 2016
Semiconductor sensor sales will achieve double-digit growth rates and record-high dollar volumes each year through 2016 as more system products gain the ability to automatically control and protect themselves, understand movement, detect changes around them, and support new user interfaces, says IC Insights’ 2012 Optoelectronics, Sensors/Actuators, and Discretes (O-S-D) Report. The new report shows sensor sales growing 18% in 2012 to $5.7 billion, surpassing the $4.8 billion record set in 2011.
Since the late 1990s, annual sensor sales have declined only once, slipping just 2% in the 2009 downturn before surging 53% in the 2010 recovery year. The solid-state sensor market grew 21% in 2011. Between 2011 and 2016, worldwide sensor sales are expected to increase by a compound annual growth rate (CAGR) of 18%, growing to $10.9 billion in the final forecast year of the new 2012 O-S-D Report (see Figure).
Within the sensor market segment, accelerometers and gyroscope devices (i.e., acceleration and yaw sensors) continue to be the largest and fastest-growing product category, with dollar volumes projected to increase by a CAGR of 20% to $5.9 billion in 2016 compared to $2.4 billion in 2011. Sales of magnetic-field sensors, such as Hall-effect devices and electronic compass chips, will grow by a CAGR of 16% to $2.7 billion in 2016 from $1.3 billion in 2011, according to IC Insights’ new O-S-D Report. Pressure sensor sales are expected to rise by a CAGR of 15% to $2.0 billion in 2016 from about $1.0 billion in 2011.
Accelerometers and gyroscope devices, along with most pressure sensors, use microelectromechanical systems (MEMS) structures to measure and detect changes around them. MEMS-based devices now account for about 70% of total sensor revenues compared to 54% in 2005. The 2012 O-S-D Report shows MEMS-based sensors sales growing by a CAGR of 19% between 2011 and 2016. Sensors are part of a broader semiconductor market segment that also includes actuators, such as micro-mirror devices, surface-acoustic wave (SAW) filters, microfluidic chips, inkjet nozzle components, and other MEMS-based products that initiate physical actions from electronic signals. Sensor sales accounted for 56% of this market’s overall sales in 2011, while actuators represented 44%, or $3.7 billion, last year. MEMS-based actuator sales are expected to grow by a CAGR of 15% to $7.5 billion in 2016, according to the new O-S-D Report’s five-year forecast.
