▎ 摘　　要

Using a 3D stretching method, a highly elastic reduced graphene oxide (rGO)/polyacrylic ester hierarchically wrinkled elastic transparent conductor (HWETC) is fabricated. Periodic hierarchical N-rGO layer wrinkling allows the HWETC to show high conductivity (100-457 Omega rectangle(-1)) and transmittance (67-85%) under substantial stretching (> 400%) and bending deformation (approximate to 180 degrees), which enables electro-thermal actuation and strain sensing.
