Whose MEMS sensor is the most popular

This article will discuss accelerometers, electronic compasses, and gyroscopes used in today's smart devices; since July 2012, Teardown.com has published 83 disassembly analysis reports. Covering mobile phones, tablet devices, notebook computers and other products, we are looking for products that span various manufacturers, prices and markets as samples.

Statistics of the number of MEMS sensors found in the accelerometer, electronic compass, and gyroscope from the sample device are shown in the table below. It is clear that the accelerometer and the electronic compass surpass the gyroscope in quantity, but we also find that the acceleration Cases where the gyroscope and the gyroscope are integrated in the same package are becoming more and more common. We also see a small number of cases where the accelerometer and the electronic compass are integrated in the same package.

Accelerometers currently on the market for triaxial accelerometers include Bosch Sensortec, ST, Invensense, Rohm Kionix, and Freescale. The number of the top three components in our analysis sample is Invensense's MPU-6050 (10 models available). The equipment used), Bosch Sensortec's BMA250 (with eight devices), and BMA255 (seven devices) also from Bosch Sensortec.

These components are mature products (first discovered in mid-2012), and it seems that the first two are close to the product life cycle. We expect that Bosch Sensortec's BMI055 will be the most popular component among the various devices on the market together with Invensense's MPU-6500 and ST's LSM3xx series components. These upcoming components are combined with accelerometers and gyroscopes. . The following table is the statistics of each vendor's acceleration count and occupancy rate from the sample.
