Abstract:
A method for processing light signals received by the eye of a human or other animal, the method comprising:providing at least first and second carbon nanotube (â€œCNTâ€ ) towers, each including at least one carbon nanotube and having a height of at least 25-200 &mgr;m, adjacent to a retina of a subject, in a sub-retinal or epi-retinal location, and positioned so that a tip of a first end of each of the first and second CNT towers penetrates the retina a selected distance in a range of about 25-200 &mgr;m and the tip is located within at least one of a ganglion layer and a bipolar layer of the retina, where a second end of each of the first and second CNT towers is connected with at least first and second spaced apart, light-receiving pixels, respectively, in a photodetector array of pixels; allowing the first and second pixels to receive first and second electromagnetic signals, respectively, from an incident light signal and to produce first and second pixel electrical signals, respectively, in response thereto; allowing the first and second pixel electrical signals to be transported in the first and second CNT towers, respectively, and to provide first and second resulting electrical signals at the first ends of the respective first and second CNT towers; and allowing the first and second resulting electrical signals to move into at least one of the ganglion layer and the bipolar layer in the retina.
