Electrochemical characterization of 16-channel soft cuffs. A Impedance spectra presented as mean ± std. dev (n = 16) at each decade, in 5 testing configurations. B Extracted impedance at 1 kHz in same testing conditions. C Average voltage measured on 16 electrodes (stimulation with 100 μA biphasic pulses) in 5 different conditions. D Extracted minimum voltage during stimulation for 16 channel soft Error bars (A,B and D) and shaded areas (C) represent standard deviation
