STMicro's six-axis e-compass uses two MEMS chips to cut power in half and boost resolution.
Better e-compasses will debut soon on smartphones, personal navigators and touchscreen tablets thanks to STMicroelectronics NV new model that extends the battery life of mobile devices. The new MEMS combines a three-axis accelerometer with a three-axis magnetometer, cutting the power by 50 percent and boosting magnetic sensitivity by 30 percent in the process. Look for longer battery life soon in mobile devices with e-compasses.
