摘要
Breathable and stretchable conductive materials are ideal for healthcare wearable electronic devices.However,the tradeoffbetween the sensitivity and detection range of electronic sensors and the challenge posed by simple-functional electronics limits their development.Here,inspired by the bionic-leaf vein conductive path,silver nanowires(AgNWs)-Ti_(3)C_(2)T_(x)(MXene)hybrid structure assembled on the nonwoven fabrics(NWF)is well sandwiched between porous polyborosiloxane elastomer(PBSE)to construct the multifunctional breathable wearable electronics with both high anti-impact performance and good sensing behavior.Benefiting from the high conductive AgNWs-MXene hybrid structure,the NWF/AgNWsMXene/PBSE nanocomposite exhibits high sensitivity(GF=1158.1),wide monitoring range(57%),controllable thermal management properties,and excellent electromagnetic interference shielding effect(SE_(T)=41.46 dB).Moreover,owing to the wonderful shear stiffening effect of PBSE,the NWF/AgNWsMXene/PBSE possesses a high energy absorption performance.Combining with deep learning,this breathable electronic device can be further applied to wireless sensing gloves and multifunctional medical belts,which will drive the development of electronic skin,human-machine interaction,and personalized healthcare monitoring applications.
