摘要：

为实现用智能坐垫监测人体坐姿,对人体健康进行辅助治疗的目的,以6种不同规格的经编间隔织物为介质层制备压力电容传感器,研究经编间隔织物压力电容传感器的静态性能。对6种传感器进行电力学性能测试,得到应力-电容曲线,结合经编间隔织物的压缩性能,将间隔织物电容传感器的应力-电容曲线划分为3个阶段,分别研究每个阶段的灵敏度和线性度。结果表明:随着压力的增加,压力电容传感器的线性度会逐渐变差;其灵敏度,呈现出先逐渐增加,而后逐渐减小的趋势。在间隔织物的压缩平台区,电容传感器灵敏度最大,在间隔织物压缩的弹性区,电容传感器线性度最好。

关键词: 间隔织物, 压力电容传感器, 灵敏度, 线性度

Abstract:

In order to achieve the intelligent cushion monitoring human sitting posture to assist human health, six types of warp-knitted spacer fabrics were used as the dielectric layer to prepare pressure-capacitance sensors. The static performance of warp-knitted spacer fabric pressure-capacitance sensors was studied. Compression and electrical experiments were performed on six kinds of sensors to obtain a stress-capacitance curve. Combining the compression performance of the warp-knitted spacer fabric, the stress-capacitance curve of the sensor was divided into three stages, and the sensitivity and linearity of each stage were studied. The results show that as the pressure increases, the linearity of the capacitive pressure sensor gradually deteriorates. The sensitivity of the capacitive pressure sensor gradually increases and then gradually decreases. In the compressed platform area of the spacer fabric, the capacitive sensor has the greatest sensitivity, and in the elastic area where the spacer fabric is compressed, the capacitive sensor has the best linearity.

Key words: spacer fabric, pressure capacitive sensor, sensitivity, linearity
