Figure 6

Nyquist plots (a–b) of the same channel over time from representative Type 1 (left) and Type 2 (right) arrays. Black dot indicates impedance at 1 kHz. Magnitude impedance (c) at 1 kHz from the same implants averaged across channels over time. Bracket indicates group-wise encapsulation effect (p < 0.001), and * indicates significant difference on weeks 0, 3–4, 5–8, and 11–12 with p < 0.002 from Bonferroni corrected pair-wise test. Note a more pronounced semicircular feature at the high impedance region of Type 1 arrays accompanied by a northeast shift in impedance at 1 kHz.
