摘　　要：为解决传统的电容式压力传感器灵敏度低的问题,基于聚丁二酸丁二醇酯对苯二甲酸丁二醇酯(PBST)和离子液体(ILs),采用静电纺丝技术制备离子介电层(ILs/PBST),并利用离电式压力传感机制开发了一种灵敏、透气的全纳米纤维离电式柔性压力传感器。该器件具有超高灵敏度(902.4 kPa-1,0~6 kPa)和快速响应/恢复时间(147 ms/147 ms),能够快速稳定地监测多种人体运动及生理信号。此外,三维多孔纳米纤维网络赋予其良好的透气性,确保其长期佩戴的舒适性,该器件有望应用在智能医疗领域。Based on poly(butylene succinate-co-terephthalate)(PBST)and ionic liquids(ILs),this paper prepared ionic dielectric layers(ILs/PBST)by electrospinning technique,and developed a sensitive and breathable all-nanofiber iontronic flexible pressure sensor.The device has ultra-high sensitivity(902.4 kPa-1,0~6 kPa)and short response/recovery time(147 ms/147 ms),which enables fast and stable monitoring of a wide range of human motion and physiological signals.In addition,the three-dimensional porous nanofiber network endows it with good breathability,ensuring its long-term wearing comfort.Therefore,the device is expected to be used in smart medical applications.
