Ultrafast–response/recovery flexible piezoresistive pressure sensors with DNA–like double helix yarns for epidermal pulse monitoring
A key challenge in textile sensors is to adequately solve the hysteresis for more broad and exacting applications. Unlike the conventional strategy in integrating elastic polymers into the textile, the hysteretic issue is critically addressed here through the structural design of yarns to provide a twisting force. The underlying mechanism is fully discussed based on…
