摘　　要：Wearable electronics have promising applications in human-machine interfaces due to their excellent flexibility,stretchability and human friendliness,and one of the key points of wearable electronics is to develop strain sensors with high sensitivity and working range.Herein,a high-performance Eco-flex@AgNW/graphite/Pt hybrid strain sensor was fabricated by suction filtrating,transferring and surface sputtering sequentially.The suction filtrating of AgNW and graphite dispersions on a wrinkle-shape Nylon filter,transferring of AgNW/graphite layer onto Ecoflex and further surface sputtering by Pt allow the construction of fingerprint bionic Ecoflex@AgNW/graphite/Pt hybrid strain sensor.The resul-tant fingerprint bionic hybrid strain sensor possesses high sensitivity of 2064.1 at the strain of 140%e155%,a wide working range of 0e155%,a short response time(111 ms and 189 ms for tensile and releasing process)and excellent cyclic stability over 5000 cycles.This study provides a universal tech-nique for the preparation of strain sensors with promising applications in the field of next-generation intelligent wearable electronics.
