9DOF Motion tracking Sensors

Motion tracking platform for mobile solutions

2M NODEs is a state-of-the-art development platform for the analysis and reporting of human kinematics. The mobile centric platform features high-accuracy wearable inertial sensors, an easy-to-integrate mobile API/SDK (Matlab and Unity) and expertise and support from the 2M engineering team. For specific applications 2M can quickly turn these developments into medically certified end-products. 

Wearable sensor platform

NODEs is a modular solution available in different executions:

  • Low latency wired NODEs
    A wired NODEs system works with strings of 1-4 NODEs per string. A main unit can connect 1-5 strings. This provides solutions from 1 to 20 sensor NODEs depending on the needs of the application. Benefit of a wired solution is the ease of setup.

  • Fully wireless NODEs
    For applications that require between 1-6 sensor NODEs there is also a full wireless motion sensing solution available.

From 1 upto 20 sensor NODEs

Nodes represents a new class of highly-scalable, low-latency real-time wireless inertial and orientation sensors. Solutions can consist of 1 upto 20 NODES depending on your application needs.

Direct interface to Unity or Matlab

2M NODEs directly interface to Unity and Matlab through the easy-to-integrate mobile API/SDK. 2M provides community support to make integration of these sensors easy.

Designed for medical use

NODES is designed for day to day practical use in a professional or home rehabilitation setting. The sensor NODEs can quickly be placed and calibration is easy also for patients with certain movement restrictions.


Motion sensor network

The NODEs motion sensor network consists of 1-20 9DOF motion sensors that sample and transmit motion or raw orientation information at high data rates in a fully synchronized manner wirelessly to a mobile device or computer. 

The NODES software enables real-time visualization of sensor data, as well as over-the-air reconfiguration of the sensors and wireless parameters. All data retrieved by the NODES Studio software is logged for post-analysis.

Bluetooth or Bluetooth Low Energy

The sensor data is transmitted using the low-power 2.4 GHz wireless Bluetooth radio from a central node to the mobile device or computer. 

9DOF motion tracking sensors

Each NODE features a complete set of 3-D digital sensors, offering 9 DOF sensor data: acceleration, turn rate (gyroscope) and magnetic field intensity (compass). Full 3D orientation information, expressed as quaternions, is also made available to the user. Users can also select the raw data rate mode.

Optimized for ease of use by care providers

Technology is often optimized for use by tech-savvy people, engineers and researchers. With NODES we focussed on creating solutions which are easy to use especially by people that are not necessarily living and breathing technology.

NODES is developed in close cooperation with a number of leading hospitals and therapists in the Netherlands. 

Motion tracking sensor applications

Nodes 9D Motion Tracking Solution for rehabilitation and VR rehabilitation gaming


2M motion trackers provide highly accurate orientation and raw measurement data for health applications, including physical therapy, rehabilitation and prosthetics, where real-time movement monitoring is crucial. Highly accurate data and movement recordings keep patients engaged with the therapy and health caregivers to evaluate their patient’s recovery progress, through the use of valuable and reliable information.

Motion Tracking Sensor Solution


Elite athletes and sport professionals always strive for excellence and self-improvement. 3D motion tracking sensors provide essential data to improve performances, monitor technical form and prevent injury. 2M motion tracking sensors provide real-time motion data capture in any environment, from the running track to the swimming pool, giving athletes and coaches a new mean to work on their goals and achieve great results.
