Towards a bacteriorhodopsin-silicon neuromorphic photosensor.
We describe our efforts towards constructing a hybrid protein-silicon neuromorphic photosensor based on the photo-active protein bacteriohodopsin. This protein displays an differential photosensitivity similar to the response of the receptive field of an X-type retinal ganglion cell. Similar bacteriohodopsin photoelectrode arrays display inherent edge detection and motion enhancement. We discuss challenges associated with constructing and understanding the protein-silicon interface and possible chemical solutions for our experimental device.
