Artificial retina made from biocompatible graphene. 18 August 2014 Physicists at Technische Universität München (TUM) are using graphene to produce key elements of an artificial retina. Graphene is thin, transparent and has a tensile strength greater than that of steel. In addition, it is a better conductor of electricity compared to copper; and, since it comprises a single layer of carbon atoms, it is considered two-dimensional. A team of researchers led by Dr. Jose A. Retina implants can serve as optical prostheses for blind people whose optical nerves are still intact. The implants convert incident light into electrical impulses that are transmitted to the brain via the optical nerve. Although various approaches for implants exist today, the devices are often rejected by the body and the signals transmitted to the brain are generally not optimal.
In contrast to the traditionally used materials, graphene has excellent biocompatibility thanks to its great flexibility and chemical durability. How the PumpTire Works. Engineering Interact - Interactive science & engineering for 9-11 year olds | technologies. Discover Engineering.
