Опубликована: Июль 27, 2023

Soft capacitive pressure sensors with high performance are becoming increasingly in demand the emerging flexible wearable field. While fiber have achieved sensitivity, their sensitivity range is limited to low-pressure levels. As typically require preloading and fixation, this narrow of poses a challenge for practical applications. To overcome limitation, study proposes resistive-capacitive hybrid response (HFPSs) three-layer core–sheath structures. The trigger enhancement mechanisms determined through model analysis experimental verification. By adjustment response, attenuation HFPSs alleviated significantly. obtained results demonstrate that excellent characteristics such as fast low hysteresis, wide frequency, small signal drift, good durability. enhances various With enhanced can effectively monitor pulse signals at preloads ranging from 0 22.7 kPa. This improves fault tolerance monitoring expands potential application scenarios sensors.
