response of the PVDF/AgNP/Mxene hybrid sensor at 1 Hz for the detection of human motion, with regard to the
driving frequency. The sensors exhibit superior stability exceptional flexibility and energy-harvesting capabilities of

as they can run consistently for over 1 week (one cycle of detecting the clapping of hands, moving of arms, moving
1,000 s per day) without performance deterioration. of fingers, and walking.
