|a Humidity sensors have received considerable attention in recent years because of their significance and wide applications in agriculture, industries, goods stores, and medical fields. However, the conventional humidity sensors usually possessed a complex sensing mechanism and low sensitivity and required a time-consuming, labor-intensive process. The exploration for an ideal sensing material to amplify the sensitivity of humidity sensors is still a big challenge. Herein, we developed a simple, low-cost, and scalable fabrication strategy to construct a highly sensitive humidity sensor based on polymer/gold nanoparticle (AuNP) hybrid materials. The hybrid polymer/AuNP aerogel was prepared by a simple freeze-drying method. By taking advantage of the conductivity of AuNPs and high surface area of the highly porous structure, the hybrid poly- N-isopropylacrylamide (PNIPAm)/AuNP aerogel showed high sensitivity to water molecules. Interestingly, the hybrid PNIPAm/AuNP aerogel-based humidity sensor can be used to detect human breath in different states, such as normal breath, fast breath, and deep breath, or in different individuals such as persons with illness, persons who are smoking, and persons who are normal, which is promising in practical flexible wearable devices for human health monitoring. In addition, the humidity sensor can be used in whistle tune recognition
