【摘要】 为弥补可穿戴电子设备舒适性差、性能单一的问题，采用镀镍机织物作为电极和针织物作为介电层，组装制备全纺织基双模态传感器，并对全纺织基双模态传感器的形貌特征、传感性能、穿戴舒适性能等方面进行测试分析。研究结果表明：织物基双模态传感器透气性和透湿性分别为168.20 g/（m²·h）、537.86 mm/s,并且可以连续实时监测非接触和压力双模信号；非接触模式下感应距离为10 cm,最大相对变化量为11%,最大灵敏度为0.022 cm^-1;压力感知范围最高达400 kPa,耐久循环可达8 000次，可检测到低至5.88 Pa的微小压力。更多还原

【Abstract】 In order to improve the comfort and performance of flexible wearable electronic devices, fabric-based bimodal sensors were assembled. Nickel-plated woven fabrics were used as electrodes, and knitted fabrics were selected as dielectric layers. Then, the morphological characteristics, sensing performance and wearing comfort of this sensor were analyzed. The results show that the air permeability and moisture permeability of the all-textile bimodal sensor are 168.20 g/（m²·h） and 537.86 mm/s, respectively. And the touchless and tactile bimodal signals can be continuously monitored in real time. In the touchless mode, the sensor exhibits the sensing distance is 10 cm, the maximum relative variation is 11%, and the maximum sensitivity is 0.022 cm^-1. Moreover, it has the pressure sensing range of up to 400 kPa, durability of 8 000 cycles, and can detect an ultralow detection limit of 5.88 Pa.更多还原
