Figure 8.

Example of VRM method applied to a 100 μm thick TPU-CCTO composite. The input voltage ramp-up/down was 5 V/s, and the flat top voltage 100 V. Experimental data (blue marks) are outputs from the picoammeter. The red solid curve corresponds to the best fit made to the data with the analytical curve representing the electrical model of Figure 6a. Referring to that scheme, the solid green curve represents the contribution due to the current through R and C, while the solid purple curve shows the contribution of the currents flowing through C1 and C2.
