a Linear (A-A’) and b transversal E-field distributions at INL level for planar and 80-μm-protruding MEA at: thresholds (Ith) of (i) protruding and (ii) planar MEAs, and the onset of inter-channel interference (Imax) for (iii) planar and (iv) protruding MEAs. White dashed lines indicate the contour of the suprathreshold (activated) area. c Ith and DR of MEA with increasing heights of protrusion. d Linear (A-A’) E-field profiles at INL induced by MEA with varying protrusion heights, all injecting Ith. e Stimulation resolution represented by Michelson Contrasts depending on protruding heights and electrode pitches.
