Wearable Full-Body Inertial Measurement Unit (IMU) Motion Capture System

The National Institute of Standards and Technology (NIST) is seeking a wearable, portable full-body Inertial Measurement Unit (IMU) motion capture system. The system must function without fixed optical camera infrastructure and capture high-fidelity human skeletal data. The acquisition includes hardware and software for the development of a motion action dataset. The system should have at least 17 sensors per suit, a sampling rate of at least 60 Hz, and support standard subject calibration and body model scaling. The contractor should describe how the system addresses magnetic interference and drift. The system should also support export of time-series motion data and SMPTE timecode synchronization with external systems. Key features of the system include: • Wearable, portable full-body IMU motion capture system • Full-body coverage with at least 17 sensors per suit • Sampling rate of at least 60 Hz • Supports standard subject calibration and body model scaling • Addresses magnetic interference and drift • Supports export of time-series motion data • Supports SMPTE timecode synchronization with external systems
