Figure 12.

Recording examples that compare dot and mixed configurations. The stimulation artifacts (SAs) and compound action potentials (CAPs) appear chronologically in the left inset without the induced simulated myoelectric signal (SMES). Recordings from both configurations were obtained during the same session. Since the “end effect” was found negligible for 5 mm inwards contact displacements in our experiments, the difference in SNR can be mostly attributed to the change between ring and dot outer contacts. This resulted in an average IR(SMES) = 2.91 (m+.-.+/d.+-+.) and IR(SA) = 1.80 (m+.-.+/r.+-+.).
