Figure 2: Electrical and mechanical properties of the porous electrode.
From: Solderable and electroplatable flexible electronic circuit on a porous stretchable elastomer
(a) Normalized electrical resistance on 10% (blue line, s.d.: ±0.044), 20% (orange line, s.d.: ±0.203) and 30% (green line, s.d.: ±0.289) stretching of the electrode for the analysis of hysteresis (empty symbols: contraction and full symbols: releasing). (b) Resistance changes during 20,000-cycle tests under 10% (blue), 20% (orange), or 30% (green) strains with 5% per second strain rate. The inset shows the reciprocating motion system set-up used to run the cycling tests. (c) Normalized resistance under the electrode stretching as a test for electrical disconnection (inset, stretched electrode with 35% strain). (d) Electrode bending tests for 150° (green), 120° (yellow), and 90° (blue) bending along a sharp edge with different thickness of PDMS membranes (error bars indicate s.d.).
