| For years, scientists have set their sights on creating bionic eye transplants to help the blind see. Yesterday they came a step closer after announcing they had made a camera that can reproduce human vision. Teams from Illinois University and Northwestern University, Illinois, cracked the problem by creating a hemispherical elastic membrane. This was flattened so the delicate electronics could be built on to it before it was allowed to spring back to its original shape. When the flexible mesh of silicon pixels joined by tiny wires springs back, the wires take the strain, leaving the delicate pixels intact. The mesh is transferred from the membrane to a curved glass lens to produce a fully-operational camera which can then be linked to a computer so its images can be viewed. [ link ] | |
