LYON, FRANCE  – Demand for mobile devices will spur MEMS devices to new highs, the latest research indicates.

Some 2.9 billion cellphones and tablets will be sold in 2017, most of which with five to 10 MEMS devices each, says Yole Développement. The result will be a multi-billion dollar MEMS market, the firm says.

“The market for MEMS in cell phones and tablets will grow 19.8% to reach $5.4 billion in 2017,” says Laurent Robin, Activity Leader Inertial MEMS Devices & Technologies, Yole.

Three categories of MEMS devices are in high volume production today:
• Motion sensors, including accelerometers, magnetometers and more recently gyroscopes, make up the hottest market segment. It is still growing quickly and many business and technical evolutions are expected. One of them is the launch of combo sensors, which provide a higher level of integration and possibly embed sensor fusion algorithms.
• MEMS microphones, which have a bright future, driven by ECM replacement and by new functions that require multiple microphones.
• BAW filters and duplexers, which have been popular for years (Band 2 in particular), and new opportunities will appear with some of the bands that will be used in 4G standards.

Many other MEMS products are under development. Yole says novel MEMS opportunities need to be watched as they will fuel this market significantly:
• While limited to weather forecast applications today, pressure sensors are going to be used in combination with inertial sensors to provide location-based services.
• RF MEMS switches had a successful start in 2011 and will benefit from the current hype for antenna tuning.
• Oscillators is another hot area where silicon MEMS has a high potential, both for replacing TCXO quartz oscillators and for integration of resonators.
• Another hot market is going to be MEMS auto-focus which provides significant added value compared to the existing VCM technology, but will face competition with other technologies as well.
• And many other types of MEMS are emerging: microdisplays, microspeakers, environmental sensors, touchscreen, joystick.

The rankings of the top players is evolving. ST Microelectronics was no. 3 in cellphone applications in 2009 and is now the no. 1 supplier by far, with $477 million in revenue from MEMS for cellphones and tablets in 2011. ST still dominates the MEMS accelerometer market, had an impressive start with MEMS gyroscopes, challenged only by InvenSense, and continues to expand to many other MEMS devices to become a one-stop supplier. ST's major clients are Apple, Samsung, Nokia, RIM and HP.

Other large players are very focused on their core markets: AKM is no. 2, with $260 million in sales of magnetometers for electronics compass solution, Avago is leading the BAW filters and duplexers market with $244 million in sales, and Knowles is no. 4 with $233 million in revenues from MEMS microphones.

里昂，法国 - 为移动设备将创出新高带动MEMS器件的需求，最新的研究表明。

其中大部分将在2017年售出约2.9亿美元的手机和片剂，用5至10 MEMS器件，Yole发展署说。其结果将是一个多亿美元的MEMS市场，该公司说。

“对MEMS在手机和平​​板电脑市场将增长19.8％，在2017年达到54亿美元，说：”洛朗·罗宾，活动负责人的惯性MEMS器件与技术，Yole的。

三类MEMS器件在大批量生产的今天：
•运动传感器，包括加速度计，磁力计和陀螺仪最近，弥补炙手可热的细分市场。它仍然迅速增长，预计许多业务和技术的演进。其中之一是推出组合传感器，它提供了更高层次的集成和可能嵌入传感器融合算法。
•MEMS麦克风，其中有一个光明的未来，由ECM更换和新功能，需要多个麦克风的驱动。
BAW滤波器和双工器，它多年来一直流行（尤其是带2），和新的机遇会出现一些带将在4G标准使用。

许多其他的MEMS产品正在开发中。 Yole公司说，新型MEMS机会需要关注，因为他们将推动这个市场的显着：
虽然有限的天气预报应用的今天，将要使用的压力传感器，惯性传感器的结合，提供基于位置的服务。
•射频MEMS开关有一个成功的开始，并在2011年将从目前的炒作天线调谐。
•振荡器是另一种硅MEMS具有高潜力的热点区域，取代TCXO的石英振荡器和谐振器集成。
另一个市场热点将是MEMS的自动对焦，提供了重要的附加值相比，现有的VCM技术，但将面临与其他技术的竞争。
•和许多其他类型的MEMS新兴微型，microspeakers，环境传感器，触摸屏，操纵杆。

顶尖选手的排名正在发生变化。 ST微电子是没有。 3，在2009年的手机应用，现在是没有。 1供应商，到目前为止，与MEMS收入在2011年的手机和片477万美元。 ST仍然占主导地位的MEMS加速度计市场，有一个令人印象深刻的MEMS陀螺仪开始，仅由InvenSense的挑战，并继续扩大到许多其他的MEMS器件成为一个一站式的供应商。 ST的主要客户有苹果，三星，诺基亚，RIM和惠普。

其他大的球员都非常注重自己的核心市场：AKM的是没有。 2，磁力电子罗盘解决方案销售的260万美元，Avago是领先的BAW滤波器和双工器的市场销售244万美元，诺尔斯没有。 4 MEMS麦克风的收入$ 233亿美元。
