Phosphoenix is developing a neural interface to restore rudimentary sight to blind individuals. The interface uses high-density and ultra-flexible probes to stimulate nerve cells in parts of the brain responsible for vision. By activating specific combinations of electrodes, it generates recognizable shapes and patterns, enabling blind individuals to identify objects and navigate their surroundings. Phosphoenix’s novel Fountain Probe design enhances the volumetric distribution of electrodes within the targeted brain region, surpassing previous approaches by orders of magnitude and optimizing the restoration of vision.
