Figure 3. Electrical performance of conformal electrodes and flexible stretchable wires. (A) The image of a flexible stretchable wire and its strain-resistance variation rate (R/R0) curve; (B) Time-dependent resistance ratio of the wire under strain amplitudes varying from 50% to 330%; (C) Resistance ratio of the wire during 5,000 stretching cycles; (D) Long-term resistance monitoring of the conformal electrodes and stretchable wires; (E) Temperature-dependent resistance variations of the conformal electrodes and stretchable wires; (F) Resistance ratio variations of the stretchable wire and images of corresponding motions; (G) Images and schematics comparing skin attachment of the conformal electrodes with copper electrodes; (H) Images of the conformal electrodes adhered to human joints and fingers; (I) Impedance-frequency characteristics of the conformal electrodes compared to copper and Ag/AgCl electrodes.
