Preparation and Performance of All-nanofiber Iontronic Flexible Pressure Sensor
Based on poly( butylene succinate-co-terephthalate) ( PBST) and ionic liquids ( ILs) ,this paper pre-pared 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.
