Bidirectional self-healing neural interface

A bidirectional self-healing neural interface, comprising:

• a first elastic substrate;
• a metal pad disposed on the first elastic substrate and having a plurality of holes defined therein;
• a neural electrode that comprises a conductive polymer composite, that is disposed on the first elastic substrate, and that is bonded to the first elastic substrate via the plurality of holes in the metal pad;
• and
• a second elastic substrate disposed on the neural electrode,
• wherein the conductive polymer composite comprises:
• a matrix formed of a self-healing polymer material;
• and
• a plurality of electrical conductor clusters distributed in the matrix,
• wherein each of the electrical conductor clusters comprises:
• particles of a first electrical conductor;
• and
• a plurality of particles of a second electrical conductor formed of the same material as that of the first electrical conductor, distributed around each of the particles of the first electrical conductor, and having sizes that are smaller than those of the particles of the first electrical conductor.
