a Experimental setup using the interface test device. b Potential of load (skin+interface) under 3 mA over 20 min for individual subjects (colored lines) and average (black line). c i: Average load potential over 20 min under constant currents (used to size battery packs), associated ii: isotemporal V-I curves (used to simulate battery pack discharge). d Voltage-controlled stimulations over 20 min for three subjects (i, ii, iii) e average current (over the active duration) for fixed applied voltages. Note unreliable non-monotonic relationship for voltage-controlled stimulation.
