根據(jù)市場研究公司IC Insights的調查顯示，包括加速度與偏航傳感器市場在2012年的年成長率僅7%──這是運動傳感器半導體市場自2005年以來的最低成長。盡管成長趨緩，但2012年加速度與偏航傳感器市場銷售額仍達到了25.4億美元的新高記錄，超越2011年的23.7億美元。
根據(jù)IC Insights最新《光電元件、傳感器/啟動器與分離式元件(O-S-D)市場》報告預測，2013年加速度與偏航傳感器銷售將成長12%，達到28.4億美元，而在2014年預計還將成長19%，達到33.9億美元的市場規(guī)模。從2012至2017年，加速度與偏航傳感器的銷售預計將以17%的年復合成長率(CAGR)成長，在 2017年達到54.7億美元。
而在2007至2012年之間，根據(jù)IC Insighs OSD調查報告，加速度與偏航傳感器銷售成長了24%。
IC Insights表示，1990年代以來，利用基于MEMS技術的加速度和陀螺儀設備已經從汽車安全系統(tǒng)擴展到新的傳感器應用，如手機、平板電腦、視訊游戲控制器、媒體播放器以及其他可攜式消費類產品。越來越多的低成本慣性傳感器被用在可攜式產品中嵌入自動化控制功能，并支援基于運動測量的更高階系統(tǒng)智慧功能。

隨著加速度/偏航傳感器進入更多高容量的系統(tǒng)應用，基于MEMS慣性元件的營收自2005年以來履創(chuàng)新高。根據(jù)IC Insights的調查資料顯示，加速度/偏航傳感器的銷售在2008年首次超過10億美元，并于2011年達到超越20億美元大關。IC Insights預測，這一市場將在2014年超過30億美元，并于2015年達到50億美元大關。
加速度度/偏航傳感器元件出貨量也正快速成長，在2012年達到27.5億只出貨量的新高記錄，較2011年的23億只增加了20%，IC Insights預測2013年全球加速度度/偏航傳感器出貨量可望持續(xù)成長20%，達到33億只的市場規(guī)模。
然而，慣性傳感器平均銷售價格(ASP)正快速下滑，IC Insights表示。慣性傳感器的ASP在2012年下跌了10%，同時也是首次跌破1美元，部分原因在于設備供應商為了提供大量應用而形成激烈競爭。 新的OSD報告預期，2013年加速度/偏航傳感器的ASP將再下跌7%至86美分。
預計在未來的幾年，ASP將較為穩(wěn)定，自2012年至2017年，平均每年下滑約2%。

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.
