Figure 4. (A) Illustrations of the pre-stretched OECT fabrication process; (B) the g_m and I_on dependence on stretching cycles for psh-DPP-g2T (ε_ps = 100%) OECTs under 0% and 30% elongation strains and the g_m/I_on data for psh-DPP-g2T (ε_ps = 150%) OECTs under various strains (from 0% to 150%); (C) EPSCs triggered by multiple spikes (each spike, -0.7 V, 100 ms; interval, 100 ms) under 0% and 60% elongation strains in the ε_⊥or ε_∥direction.
