Abstract

The fabrication of a retinal implant capable to restoring vision to the blind requires access to the right materials and processes. In the past few years, carbon materials, in particular diamond and graphene, have proved to be of exceptional value in the creation of devices which can stimulate and record from neural tissue, including the retina. However, the properties that make these materials so attractive, such as chemcial stability, also make them hard to process. Laser processing offers the ideal solution to this problem. In this talk I will outline how we use lasers to create mutlielectrode diamond feedthrough arrays, and how lasers can be used to create a hermetic seal which encapsulates the electronics and protects the device from degradation due to exposure to the body for the lifetime of the patient. I will summarize by explaining how all these processes and materials are combined in a new generation of retinal implant: the diamond eye
