Figure S1. I–V curves of the DNA sensor under different compressive strains and target cDNA concentrations: (a) -0.25%, (b) -0.36%, (c) -0.45% compressive strain with the target cDNA concentration ranging from 0 M to 1×10-7 M: (d) 1×10-8 M, (e) 1×10-9 M, (f) 0 M target cDNA concentration with the compressive strains ranging from 0.00% to -0.59%.
Figure S2. I–V curves of the DNA sensor under (a) -0.36%, (b) -0.59% compressive strain with the non-cDNA solution with the concentration ranging from 0 M to 1×10 -7 M.
