MEMS for cell phones and tablets 2013 Report by Yole Developpement

Description:

From a $ business in 2012 to $ by 2018! Market demand for new sensors will lead to a $ market by 2018! MEMS devices are proliferating in mobile devices. We count 25+ sensors and actuators in production or in development for mobile applications, including MEMS accelerometers, MEMS gyroscopes, magnetometers, 6-axis e-compasses, 6-axis IMU combos, 9-axis combo solutions, silicon microphones, microspeakers, pressure sensors, humidity/temperature sensors, BAW filters and duplexers, MEMS switches and variable capacitors, silicon MEMS oscillators/resonators, micromirrors for picoprojectors, microdisplays, MEMS autofocus, IR sensors and micro bolometers, biochemical detectors & gas sensors, MEMS touchscreen, MEMS joystick, radiation detectors, MEMS fuel cells, energy harvesting, UV sensors, ultrasonic sensors and more! Mobile phones and tablets are becoming more sophisticated, and MEMS content is everincreasing. Indeed, MEMS sensors and actuators bring a strong value proposition at different levels: •Navigation & environmental sensing •Improved sound quality •Better communication performance •Improved visual experience + new tactile interface •Increased battery life •Infrared sensing The past 12 months have seen big changes. While in the past, cell phone MEMS were limited to three categories (inertial, microphones and filters), we’ve seen strong adoption of new device types targeting environmental sensing. Also, pressure sensors are being heavily adopted in flagship phones and tablets, and humidity sensors are being adopted in the Samsung Galaxy S4. All of these new MEMS killer applications are detailed in this report. Changes have even occurred in existing highvolume MEMS areas: •Significant architectural changes have been observed in inertial sensors, with current strong adoption of IMU combo sensors. Likewise, a new opportunity has appeared with a camera module’s dedicated OIS gyroscope. •A trend has appeared involving integration of a third MEMS microphone to provide HD voice recording ( in the iPhone 5), in addition to the dual microphone architecture described in the last report. This trend is a market booster. •Strong adoption of LTE in high-end platforms will boost the duplexer market for the next three years. The long-term outlook for MEMS companies is brighter than ever, as existing products and products just ramping up will drive solid growth over the next few years. Additionally, a new wave of MEMS products will enable further growth. This report describes why some of these emerging MEMS (speakers, oscillators, chemical sensors, switches, auto-focus, etc.) will ramp up in volume almost overnight, just as pressure and humidity sensors did in the past few months. A nice 19% yearly growth is predicted for a market that reached $ in 2012, and volume growth will be even more impressive, with units expected by 2018, up from in 2012. Sensor fusion is heating up with its first commercial implementations! As sensor popularity enables new applications, software is key for obtaining the best performance and functionalities. Sensor hubs appeared at the end of 2012, in Windows Phone architectures and also in some Android platforms such as the Samsung Galaxy Note 2 and Galaxy S4, which integrate Atmel hub. This greatly impacts the MEMS value chain, since successful products must offer the right level of software and be qualified with sensor hubs in a timely manner. Sometime in 2013, evolution is still expected in value partitioning, in particular with sensor fusion integration in the application processor. Also, as the value chain continues moving and novel architectures appear, new killer functionalities will hit the market. In particular, an ecosystem for context awareness or indoor navigation is put in place, with technology demonstrations (such as Movea’s recent demo at CES) and release of the first commercial chipsets enabling new sensor and data fusion concepts (Qualcomm iZat, Gimbal, CSR SiRFusion Platform, etc.). The most recent end-user trends shaping demand for nextgeneration MEMS devices are carefully analyzed in this report. In fact, one of the strongest impacts on sensor fusion architecture is the growth of connected devices and the use of the cell phone as a hub. More information on the report at
