1. An apparatus configured for implantation in a body of a subject, comprising:
- a support substrate; and
at least 500 electrodes protruding at least 50 um from the support substrate, each electrode having (a) a distal tip, (b) an electrically-exposed tip portion, (c) an electrically-insulated body portion, proximal to the electrically-exposed tip portion, and (d) a cross-section of 50-200 um2, at a site 20 um from the distal tip,wherein the electrically-exposed tip portion of each electrode and the electrically-insulated body portion of each electrode are configured to penetrate retinal tissue of an eye of the subject, andwherein each electrode is less than 600 um in length.

19. A method for retinal stimulation comprising:
-
identifying a subject as suffering from a retinal disease; in response to identifying the subject, implanting in an eye of the subject an apparatus including; a support substrate; and at least 500 electrodes protruding at least 50um from the support substrate, each electrode having (a) a distal tip, (b) an electrically-exposed tip portion, (c) an electrically-insulated body portion, proximal to the electrically-exposed tip portion, (d) a length of less than 600 um and (e) a cross-section of 50-200 um2, at a site 20um from the distal tip; and positioning the apparatus such that the electrically-exposed tip portion of each electrode and the electrically-insulated body portion of each electrode penetrate retinal tissue of the eye of the subject.
