Miniaturized 9-axis Inertial Measurement Unit

Movea's wireless, miniaturized Inertial MeasurementUnit (IMU) uses MEMS sensors to measure 9 Degree-of-Freedom (DOF) motion with aPCB module. The MotionPod is a hardware solution for motion sensing thatincorporates a 3-axis accelerometer, a 3-axis gyroscope and a 3-axismagnetometer in a fully integrated package complete with software and wirelessinterface. The miniaturized MotionPod is now an off-the-shelf component.

A single MotionPod can provideinformation like range of motion, rotation, speed and acceleration. MultipleMotionPods can also be networked to gather information simultaneously fromdifferent parts of the body for applications such as performance analysis andfull body motion capture. The MotionPod measures 33 x 22 x 15 mm (1.3 x0.8 x 0.6 inch) and weighs 14 g (0.5 oz). It is designed to clip onto astrap for easy attachment to the body or to be patched directly onto the body.

MotionPods have a built-in,2.4GHz wireless transmitter for a range of up to 30 m (100 ft) with low powerconsumption to maximize battery life, providing up to 8 hours of usage. Datafrom the MotionPod is transmitted wirelessly to a receiver that's connected toa computer via a standard USB connection. Up to 32 MotionPods can beconnected to a single Motion Controller.

The MotionPod comes withMovea's SmartMotion Development Kit (SMDK) which provides a Windows-based APIallowing application developers, systems integrators and OEMs to integrate andcustomize the use of wireless multi-sensors in their applications. It alsoincludes a companion application, the MotionDevTool that has a graphical userinterface for real-time visualization and integration.
