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.
Claims34
A system for modulating nerve activation in an external portion of an amputee's skin, comprising:
- a substrate comprising:
- a first polymer layer including a plurality of electrodes configured to be in electrical communication with the external portion of the amputee's skin;
- a second polymer layer;
- and
- a plurality of conductive traces comprising a conductive ink coupled with the plurality of electrodes;
- a controller configured to:
- selectively activate one or more of the plurality of electrodes with a switching matrix as determined by the amputee via a user interface;
- transmit electrical current through the amputee's skin;
- and
- stimulate nerve fibers in the amputee's skin responsive to transmitting electrical current;
- a secondary controller in wireless communication with the controller and configured to:
- cause the plurality of electrodes to simulate at least one of tapping sensation, a kneading sensation, a rolling sensation, a cupping sensation, and a scraping sensation;
- and
- an interconnect configured for the amputee to interchangeably connect the controller and the substrate when coupled with the plurality of conductive traces.
