(A) Change in electrical resistance vs. number of bend cycles with a 15 mm bend radius of the E3 sample for 100 bend cycles. (B) Change in electrical resistance vs. number of bend cycles with a 10 mm bend radius of the E3 sample for 100 bend cycles. (C) Resistance increases due to the number of bend cycles for both E3 samples; 15 mm bend radius and 10 mm bend radius are shown in red and blue, respectively.
