MTw Development Kit

The MTw™ is a small, highly accurate wireless inertial 3D motion tracker.

The MTw sets a new standard for ambulatory 3D kinematic measurement systems - building on Xsens’ 10 years of leadership in inertial sensor technology. The MTw uses the unique Awinda™ radio protocol developed by Xsens. The Awinda protocol implements a very accurate (≤ 10 µs difference) time synchronization between multiple MTw’s in a wireless body-area network. In fact, the time synchronization is so accurate that it is comparable to the wired measurement systems from Xsens.

The Awinda Station is the link between up to 32 MTw’s (wireless) and the PC (USB). The Awinda Station has multiple hardware connections for synchronization with third party devices, using TTL levels 0-3.3V. Additionally, it charges up to 6 MTw’s simultaneously.

Specially designed click-in full body straps, improves the efficiency of preparation, reducing the time needed for subject setup.

The MTw Development Kit, incorporating multiple MTw’s, the Awinda Station, MT software and click-in body straps, is ideal for measuring motion and orientation of the human body - anywhere.
