运动传感器市场成长趋缓，惯性元件ASP连跌

根据市场研究公司IC Insights的调查显示，包括加速度与偏航传感器市场在2012年的年成长率仅7%──这是运动传感器半导体市场自2005年以来的最低成长。尽管成长趋缓，但2012年加速度与偏航传感器市场销售额仍达到了25.4亿美元的新高记录，超越2011年的23.7亿美元。 根据IC Insights最新《光电元件、传感器/启动器与分离式元件(O-S-D)市场》报告预测，2013年加速度与偏航传感器销售将成长12%，达到28.4亿美元，而在2014年预计还将成长19%，达到33.9亿美元的市场规模。从2012至2017年，加速度与偏航传感器的销售预计将以17%的年复合成长率(CAGR)成长，在 2017年达到54.7亿美元。 而在2007至2012年之间，根据IC Insighs OSD调查报告，加速度与偏航传感器销售成长了24%。 IC Insights表示，1990年代以来，利用基于MEMS技术的加速度和陀螺仪设备已经从汽车安全系统扩展到新的传感器应用，如手机、平板电脑、视讯游戏控制器、媒体播放器以及其他可携式消费类产品。越来越多的低成本惯性传感器被用在可携式产品中嵌入自动化控制功能，并支援基于运动测量的更高阶系统智慧功能。

随着加速度/偏航传感器进入更多高容量的系统应用，基于MEMS惯性元件的营收自2005年以来履创新高。根据IC Insights的调查资料显示，加速度/偏航传感器的销售在2008年首次超过10亿美元，并于2011年达到超越20亿美元大关。IC Insights预测，这一市场将在2014年超过30亿美元，并于2015年达到50亿美元大关。 加速度度/偏航传感器元件出货量也正快速成长，在2012年达到27.5亿只出货量的新高记录，较2011年的23亿只增加了20%，IC Insights预测2013年全球加速度度/偏航传感器出货量可望持续成长20%，达到33亿只的市场规模。 然而，惯性传感器平均销售价格(ASP)正快速下滑，IC Insights表示。惯性传感器的ASP在2012年下跌了10%，同时也是首次跌破1美元，部分原因在于设备供应商为了提供大量应用而形成激烈竞争。 新的OSD报告预期，2013年加速度/偏航传感器的ASP将再下跌7%至86美分。 预计在未来的几年，ASP将较为稳定，自2012年至2017年，平均每年下滑约2%。 编译：Susan Hong 参考原文：Motion sensing IC growth slowing，by Dylan McGrath

{pagination} The high-flying acceleration and yaw sensor product category was brought back to earth in 2012 when price erosion pulled down annual sales growth to 7%—the lowest percentage increase for motion-sensing semiconductors since 2005, according to IC Insights’ new 2013 O-S-D Report—A Market Analysis and Forecast for Optoelectronics, Sensors/Actuators, and Discretes. Despite slower growth, acceleration/yaw sensors—which are accelerometers and gyroscope devices primarily made with microelectromechanical systems (MEMS) technology—reached record-high sales of $2.54 billion in 2012, surpassing the previous peak of $2.37 billion in 2011, when market revenues rose 27%. The new O-S-D Report shows acceleration/yaw sensor sales rising 12% in 2013 to $2.84 billion, followed by a 19% increase in 2014 to $3.39 billion (see figure). Between 2012 and 2017, acceleration/yaw sensor sales are projected to rise by a compound annual growth rate (CAGR) of 16.6%, reaching $5.47 billion in the final year of the forecast period. In the 2007-2012 period, acceleration/yaw sensor sales grew by a CAGR of 23.8%, according to the new 2013 O-S-D Report. Since the 1990s, the use of MEMS-based accelerometers and gyroscope devices has expanded from automotive safety systems (primarily in car-crash airbag triggers and electronic stability controls for steering and braking) to new sensing applications in cellphones, tablet computers, video-game controllers, media players, and other portable consumer products. A growing number of low-cost inertial sensors are being used to embed automated controls in portable products and support higher levels of system “intelligence,” based on measurements of movement. Multi-axis accelerometers and gyro devices are also being used together and combined with other types of sensors (such as magnetic-compass chips, pressure sensors, and light sensors) for multi-dimensional measurements in highly adaptive, intelligent systems that employ “sensor-fusion” software to simultaneously processes data from different devices. With acceleration/yaw sensors moving into more high-volume systems applications, revenues for MEMS-based inertial devices have reached new record-high levels each year since 2005, based on IC Insights’ market data. Acceleration/yaw sensor sales crossed the $1.0 billion level for the first time in 2008, and three years later, in 2011, the market’s revenues passed the $2.0 billion mark. The new O-S-D Report’s forecast shows acceleration/yaw sensor sales crossing the $5.0 billion level in 2017, just three years after surpassing $3.0 billion in 2014. Acceleration/yaw sensor unit shipments are also growing at strong annual rates, reaching a record-high volume of 2.75 billion devices in 2012, which was a 20% increase from the previous peak of 2.30 billion units in 2011. IC Insights is forecasting a 20% increase in acceleration/yaw sensor shipments in 2013 to 3.30 billion units worldwide. However, average selling prices (ASPs) of inertial sensors are also falling fast. In 2012, ASPs fell 10% to below $1.00 for the first time partly due to intense competition between device suppliers aiming to serve high-volume applications. The new O-S-D Report projects that acceleration/yaw sensor ASPs will drop another 7% in 2013 to $0.86. In the next several years, ASPs are expected to stabilize, resulting in an average annual decline of 2% between 2012 and 2017, according to the new report.
