ABSTRACT:
An interface for selective excitation of a biological neural network is provided. The interface includes a microelectromechanical (MEMS) device having a deformable membrane, and a tactile-sensitive neural cell disposed on the deformable membrane. The cell on the deformable membrane senses motion or deformation of the membrane and provides a signal, responsive to membrane motion or deformation, to the biological neural network. Preferably, the deformable membrane and cell have about equal areas, to provide selective excitation. An interface array including at least two such interfaces is also provided. A retinal prosthesis interface array having, in each element of the array, a photodiode within the MEMS device for electrostatically actuating the deformable membrane is also provided. For this alternative, the cells and deformable membranes are preferably transparent.
