Second generation IMU for real-time wireless and data logging applications

The Next Generation IMU (NGIMU) is a compact IMU and data acquisition platform that combines on-board sensors and data processing algorithms with a broad range of communication interfaces to create a versatile platform well suited to both real-time and data-logging applications.

Stream by USB, Serial, or Wi-Fi

Measurements can be streamed in real-time through multiple interfaces. USB provides a convenient wired connection for most operating systems. A configurable serial interface offers additional compatibility with embedded and industrial systems. Dual-band Wi-Fi provides high-performance wireless connectivity for desktop and mobile applications.

Self-Contained Data Logger

In addition to its real-time streaming capabilities, the NGIMU can function as a stand-alone data logger. The on-board microSD supports up to 32 GB for hundreds of hours of storage. A battery life of up to 12 hours and motion trigger wake up allow the NGIMU to be deployed for multiple days. Files can be downloaded by USB and converted to CSV for use with applications such as Excel, MATLAB, and Python.

Analogue and Serial Inputs

The analogue input interface provides 10 analogue input channels along with power for external sensors and signals. This can be used for force sensors and other analogue sensors. The auxiliary serial interface provides bi-direction communication, power, and general purpose digital I/O for external devices such as GPS modules. This interface can also be used for real-time control of user-designed devices for visual or haptic feedback.

Wireless Synchronisation

Wireless synchronisation means that the timestamps of all measurements are derived from a common clock. Wireless synchronisation can be achieved with any router. The Synchronised Network Kit is a preconfigured Wi-Fi router and USB charging hub. The NGIMU Synchronised Network Manager software application can be used to connect to multiple NGIMUs and log synchronised data to file for post-processing.

Open Source Software

The NGIMU software is free and open-source. The Windows GUI can be used to view real-time measurements as graphs or a 3D visualisation, and log streamed data to CSV for use with applications such as Excel, MATLAB, and Python. User software development and integration is supported by an open source C# API.

iSen Biomechanics

The NGIMU is a part of the iSen biomechanics toolkit produced by STT Systems. iSen is comprehensive solution for biomechanics applications, providing utilities for signal processing, event detection, report generation, real-time visualisations, and patient/athlete database management.
