Use of High-Frequency Radar to Capture Gait Parameters | Biomedgrid llc

Features related to gait can be fundamental metrics of human motion. Gait speed and stride length are increasingly being recognized as a measure a person's health status; changes in these parameters from a person's normal values often indicates changes in health. However, variations in gait characteristics as a result of cognitive or other conditions may go undetected as the effect can be gradual and often goes unnoticed during clinic visits. Technologies that detect changes in the gait of older adults could support detection, evaluation, and monitoring of parameters related to changes in mobility, cognition, and frailty. For better biomedical applications, it is extremely vital to extract crucial gait parameters with high accuracy while maintaining ease of use for practical implementation. We have been developing an ultrahigh-frequency radar sensor that can measure walking speed and stride length in range of indoor environments. Since our approach uses non-invasive wireless technologies, people do not need to wear or carry a device on their body. Additionally, due to the fact that there is no visual camera privacy is preserved
