TDK InvenSense PositionSense™ 2-Chip 9-Axis MEMS Sensor Solutions
TDK PositionSense™ 2-Chip 9-Axis Micro-Electro-Mechanical Systems (MEMS) Sensor Solutions provide precise orientation detection and navigation for wearables, robotics, drones, and mobile devices. The solutions combine an ultra-low-power 6-axis inertial measurement unit (IMU) with a 3-axis tunnel magnetoresistance (TMR)-based magnetometer. Integrated sensor fusion and calibration software enable fast, accurate position tracking and absolute heading detection.
PositionSense delivers reliable navigation, even in environments with limited or unavailable satellite signals. These solutions enable rapid sensor calibration and maintain accurate orientation after restarts or in the presence of magnetic interference. Low-power operation and easy integration make the TDK solutions ideal for smart glasses, smartphones, AI wearables, humanoid robots, and other physical AI devices.
