Noncontact assessment for fatigue based on heart rate variability using IR-UWB radar
Scientific Reports, 2022 Physical fatigue can be assessed using heart rate variability (HRV). We measured HRV at rest and in a fatigued state using impulse-radio ultra wideband (IR-UWB) radar in a noncontact fashion and compared the measurements with those obtained using ...
