摘      要：Flexible strain sensors exhibit outstanding advantages in terms of sensitivity and stability by detecting changes in physical *** can be easily attached to human skin and clothed to achieve monitoring of human motion and ***,general sensing material shows low stretchability and cannot respond to signals under large *** this work,a highly stretchable polymer composite was developed by adding small amount(0.17 wt.%)of silver nanowires(AgNWs)in stretchable conductive polymer *** conductivity of polymer/AgNWs composite is 1.3 S/m with the stretchability up to 500%.The stretchable strain sensor based on the polymer/AgNWs composite can respond to strain signals in real time,even for 1%strain response,and shows excellent stability over 1,000 loading/unloading ***,the strain sensor can be attached to human skin and clothed to monitor joints,throat and pulse of the human *** human body electrocardiogram(ECG)signal was detected successfully with the polymer/AgNWs electrode,which is comparable to the signal obtained by the commercial ***,the sensors enable monitoring of human movement and *** advantages make it a potential application in wearable devices and electronic skin.
