Experiment 2: Three series of applied DC voltage pulses and small signal conductance measurements after each series

<b>Description</b><br>It was possible to classify the human skin memristor either as volatile or non-volatile by this experiment. The data was collected from three different skin sites (earlobe, fingertip, forehead) simultaneously. The recordings were done on 28 test subjects. <br><br><b>Experimental Design</b><br>Experiment 2 consisted of three series of applied DC voltage pulses. The voltage steps were always from 0 V to -0.8 V (first and third series) and 0 to + 0.8 V (second series). Resulting current, i, through the skin was measured. Each single pulse had a duration of 15 seconds in high state, followed by 5 seconds in low state (0 Volts). A continuation of 9 pulses was applied; the total duration per pulse series was three minutes. Electrodermal activity (EDA) (including small-signal conductance) was measured for three minutes after each DC pulse series. The change between recording modes was performed manually. <br><br><b>File information</b><br>The recordings are presented in the same order as they were conducted. <br><br><i>"Data_experiment_2 (DC Pulse_series)"</i>: The number of samples N per signal period (including 15 seconds in high state, followed by 5 seconds in low state) is 500. The Samples 1 to 4501 in each line reflect 9 periods of the corresponding signal. <br>
