ST squeezes 9-axis sensor for use in glasses
This together with other improvements allows 9-axis inertia measurement to support motion tracking in wearable equipment, such as smart glasses, as well as in portable equipment such as smartphones and tablet computers, the company said.
A 9-axis inertial sensor combines sensing elements for 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer in a single component and can provide information for absolute orientation and dead-reckoning calculations in personal navigation systems.
As well as decreasing the size compared with previous modules, the LMS9DS1 module provides 30 percent higher magnetometer resolution and 20 percent lower overall power consumption. It also delivers a reduction in accelerometer zero-g offset, to below 100 milli-g, and reduces typical gyroscope rate noise. The typical operating current is 2mA, the company said.
"With 30 percent higher magnetometer resolution, 20 percent lower power and a footprint more than one-third smaller than other devices, designers have extra freedom to establish new form factors and improve stability and performance," said Benedetto Vigna, general manager of analog, MEMS and sensors group at ST, in a statement.
A 72-page datasheet about the LSM9DS1 could be found here when this article was first posted.
