6-axis MEMS gyro/accelerometer for gesture sensing/image stabilisation

September 17, 2015 // By Graham Prophet
This motion sensor from STMicroelectronics enables enhanced user interfaces, and image stabilisation, performed simultaneously, in products such as smartphones and tablets, while claiming the lowest power consumption and smallest package size.

In ST's iNEMOTM range of inertial motion sensors, the LSM6DS3H combines a 3-axis gyroscope, a 3-axis accelerometer, and an ultra-low-power processing circuit in a System-in-Package solution for lowest power consumption and smallest package size.

Electronic Image Stabilisation (EIS) and Optical Image Stabilisation (OIS) techniques help minimise image blurring caused by camera motion while the snapshot is being captured. Initially developed for professional cameras, these techniques are being increasingly deployed in smartphones and tablets, where blurring is most likely to occur when the user takes a photograph with an outstretched arm.

The LSM6DS3H builds on ST's expertise in designing high-end gyroscopes for OIS and the company’s role in providing dual-core gyroscopes capable of simultaneously handling both user motion and gesture recognition and camera image stabilisation. The MEMS module allows equipment manufacturers to minimise size, system complexity, and cost, with power consumption of less than 1 mA, compared to the 5 mA required by systems that employ two single-function gyroscopes.
