Abstract: A system for stimulation of a nerve and measuring impedance. The system includes a neural interface device including a plurality of electrodes; a voltage or current source operatively connected to at least a subset of the electrodes, wherein the voltage or current source is configured to generate an electrical signal to be applied to the electrodes; an impedance measuring module operatively connected to at least a subset of the electrodes, wherein the impedance measurement module is configured to measure the impedance between the electrodes; and a controller arranged to determine an amplitude of an action potential induced in the nerve, via the electrical signal, based on the measured impedance and to adjust the electrical signal in order to induce an action potential having a target amplitude.
