Application of flexible pressure sensor based on AgNWs in human motion detection

Purpose In this paper, a new flexible piezoresistive pressure sensor which uses non-woven fabric as the flexible substrate and sliver nanowires (AgNWs) as the conductive materials was reported. Design/methodology/approach The compression test of the pressure sensors was carried out at different compression frequencies and found that the sensors had more than 5,000 times reusability at high frequency. Findings When pressure sensors were applied to different parts of the human body, such as fingers, elbows, knees and throat, the sensors respond differently to different degrees of movement. Originality/value The proposed pressure sensor has broad application prospects in the human motion detection.
