Abstract
Various aspects of this disclosure relate to a layered polymer substrate with electrodes and conductive ink embedded in the substrate. In some embodiments, a prosthetic liner may be bonded onto the polymer substrate. The substrate may include an interconnect coupled to the electrodes via the conductive ink. The system may include a controller (e.g., an electrode controller) in communication with the electrodes via the conductive ink. The electrodes may be activated such that they may stimulate nerve fibers in a user's residual limb.
Claims23
A method, comprising:
- forming a substrate for nerve activation configured to be in electrical communication with an external portion of a user's skin on an extremity, including:
- forming a first polymer layer comprising a plurality of electrodes configured to electrically simulate at least one sensation and stimulate nerve fibers responsive to selective activation of any one or more of the plurality of electrodes;
- forming a plurality of conductive paths to the plurality of electrodes configured to connect with a flexible interconnect configured for the user to interchangeably connect an electrode controller and the substrate, wherein each electrode is associated with a respective conductive path;
- and
- forming, over the first polymer layer and the plurality of conductive paths comprising conductive ink, a second polymer layer, wherein the plurality of electrodes are embedded relative to an upper surface of the second polymer layer.
