Inertial Measurement Units

Definition

Inertial Measurement Units (IMUs) are devices that measure and report a body's specific force, angular rate, and sometimes magnetic field, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. These devices are crucial in capturing movement data and are increasingly integrated into sports biomechanics to analyze performance, enhance training, and improve athlete safety. As technology evolves, IMUs are becoming more sophisticated and accessible, leading to innovations in motion analysis and real-time feedback for athletes.
