We also generated artificial data based on de Levie's model (Section 2.5) by adding white noise to the de Levie impedance given in . We first varied the ionic resistance, 𝑅 ion , with 𝜎 𝑛 exp =1.00×10 -1 Ω, before we varied the resistance 𝑅 ∞ with 𝜎 𝑛 exp =2.00×10 -2 Ω. The values of the parameters are reported in Table of SI2. The frequencies ranged from 10 -3 Hz to 10 6
