Abstract

With the development of the new four modernization of automobiles, the intelligent pace of the global automobile industry has accelerated. In order to meet the demand and help the development, this paper proposes a preparation method of ZnO nanofiber flexible pressure sensor based on electrospinning technology. ZnO nanofibers prepared by electrospinning are used as the pressure-sensitive active layer, which is placed on the fork guide electric layer, and then packaged with PDMS film for protection. After preparation, a series of performance tests were carried out successively. It was observed by SEM that the pressure-sensitive active layer was long fiber with uniform distribution. XRD pattern is consistent with standard card. The results of sensitivity test and human motion sensing test show that the sensor has the characteristics of high sensitivity, short response time and stable signal sensing, which can meet the actual needs and is expected to be widely used in the field of automotive intelligent cockpit.
ZnO纳米纤维柔性压力传感器的制备及性能研究
随着新四化汽车的发展,全球汽车工业的智能化步伐加快。为了满足需求和促进发展,本文提出了一种基于静电纺丝技术的ZnO纳米纤维柔性压力传感器的制备方法。采用静电纺丝法制备的ZnO纳米纤维作为压敏有源层,置于叉导电层上,再用PDMS薄膜封装保护。制备完成后,先后进行了一系列性能测试。扫描电镜观察到,压敏活性层为长纤维,分布均匀。XRD谱图与标准卡一致。灵敏度测试和人体运动感知测试结果表明,该传感器具有灵敏度高、响应时间短、信号感知稳定等特点,能够满足实际需要,有望在汽车智能座舱领域得到广泛应用。
