1. A method of modulating nerve activation in a residual limb of an amputee, comprising:
providing a system that comprises:
a substrate comprising:
a first polymer layer with plurality of electrodes coupled with conductive ink;
a second polymer layer; and
a liner attached to the substrate, the substrate and the liner configured to attach to the residual limb such that the plurality of electrodes are in electrical communication with the residual limb;
an electrode controller configured to transmit electrical current to the plurality of electrodes according to one or more inputs;
an interconnect configured for the amputee to interchangeably connect the electrode controller and the substrate when coupled with the conductive ink;
receiving, from the amputee with a user interface of a user device configured to communicate signaling to the electrode controller, a first input corresponding to selectively activating one or more of the plurality of electrodes;
transmitting, with the electrode controller, electrical current through the residual limb at one or more locations according to the first input; and
stimulating nerve fibers in the residual limb responsive to transmitting electrical current with the plurality of electrodes.
