Millimeter-Wave Body-Centric Radar Sensing for Continuous Monitoring of Human Gait Dynamics

We present a shoe-mounted 60GHz Doppler radar for continuous, contactless gait monitoring. Foot-level micro-Doppler signatures quantify timing, symmetry, and clearance linked to neurological and musculoskeletal disorders. Trials with controlled patterns (normal, hemiplegic, festinating, freezing) show separable spectrogram features and derived metrics. The unobtrusive, privacy-preserving form factor supports early screening, objective tracking, and rehabilitation monitoring.
