Strain Sensing Stability Of 3d Printable Conductive Polymers Under Large Deformations

In this paper, two types of 3D-printable conductive inks are introduced based on PDMS, ACB/MWCNTs as main fillers. Six kinds of specimens are printed in three-layer columns to observe the printing performance at different angles. The stress-strain curves and strain sensing signals are tested under uniaxial tensile load and cyclic tensile load, respectively.
