We fabricated flexible humidity sensor which responds 10 times faster than commercial CMOS humidity sensor. Our sensor is based on Ionic-Gel-coated Fabric (IG-Fabric). We use EMIMBF_4 as ionic liquid and mixed with PVDF to fabricate ionic gel. The EMIMBF_4 has a characteristic that it absorbs H_2O. IG-Fabric has wide surface area and high gas permeability so that gases can be easily absorbed and detached. This sensor has many applications such as flu-mask-type human breath sensor, wearable sweat monitoring sensor.
