主　　题：Wearable electronics Silk fibroin Multifunctional sensing Smart clothing 

摘      要：Wearable sensing technology enables the interaction between the physical world and the digital world,as takes an irreplaceable role in development of the Internet of Things(IoT),and artificial intelligence(AI).However,increasing requirements posed by rapid development of wearable electronic information technology bring about many for wearable sensing technology,such as the demands for ultrahigh flexibility,air permeability,excellent biocompatibility,and multifunctional ***,we propose a wearable all-fiber multifunctional sensor(AFMS)based on a biocompatible material,i.e.,silk fibroin.A simple two-layer configuration of a silk fiber film and an interdigital Ag nanowires(AgNWs)electrode was designed to construct the AFMS,in which silk fibroin simultaneously serves as a fundamental supporting component and a functional sensing *** and spray coating technologies were introduced to process the silk fiber film and the AgNWs *** all-fiber configuration allows AFMS to possess ultrahigh flexibility and good air permeability,and silk fibroin enables the AFMS to have excellent *** importantly,benefiting from the all-fiber structure and the environmentally sensitive dielectric property of silk fibroin,the AFMS presented multiple sensing characteristics,including pressure sensing,temperature sensing,and humidity *** them,the pressure sensing function reached a high sensitivity of 2.27 pF/kPa(7.5%/kPa)and a remarkable resolution of~26 Pa in the low pressure ***,the outstanding mechanical reliability and sensing stability of AFMS were proven by a systematic *** addition,the AFMS was successfully applied for smart mask for breathing monitoring and a smart glove for bending angle recognition of finger *** sensing characteristics combined with prominent fundamental features enable the AFMS tremendous potential in the smart sensing field,e.g.,smart clothing.
