An analysis on leg muscles strengthening exercises by using wearable UWB technology

This work presents an analysis on leg muscles strengthening exercises utilizing wearable ultra-wideband (UWB) technology. For analysis of various exercises, channel parameters are examined by using proposed compact wearable antennas mounted on the human subject at suitable places. Moreover, SAR analysis of this antenna has also been performed which is within acceptable limit (<0.927 W/kg). The study of channel formed due to distance variation takes into account both LOS and NLOS links. For this analysis, path loss and rms delay spread have been considered as basic parameters. The differences in channel information are attributable to the antenna’s location, human body obstruction, and various activities that are being performed. The proposed wearable antenna design has a very compact size which makes it suitable for analysis that is being performed on lower limb activity monitoring having applications in healthcare industry.
