Reliability of PEDOT-PSS strain gauge on foam structure
Reliability is one important issue in using PEDOT: PSS as a strain gauge for large strain measurements. In our research,
PEDOT: PSS strain gauge is fabricated on the polyurethane and porous substrate, which enhances the mechanical
property when large strain and cyclic loads are applied to it. Our result shows that with the polyurethane as the substrate
adhesion layer, the strain of PEDOT: PSS can go up to 17.7% and stabilize without reference resistance drifting.
