摘要：
A human surrogate head model (HSHM) to measure brain/skull displacement due to a physical force, such as due to an explosive, ballistic, or automotive crash type of event. A HSHM may include a plurality of magnetic field generators positioned stationary relative to a HSHM skull, each to generate a magnetic field oriented with respect to a corresponding one of multiple directions. The HSHM may include one or more electromagnetic force (EMF)-based displacement sensors, each of which may include three inductive coils oriented orthogonally with respect to one another and co-aligned about a central point. A signal processor may be implemented to separate signals generated by each coil of each EMF-based displacement sensor into a plurality of component magnitudes, each attributable to a corresponding one of the magnetic fields. A computer-implemented model may be implemented to correlate between the component magnitudes and a corresponding position and orientation of the displacement sensor.
