Core Viewpoint - The development of the world's first wide-spectrum visual prosthesis by a collaborative team from Fudan University and the Chinese Academy of Sciences marks a significant advancement in restoring vision and extending sensory capabilities beyond natural limits [1][2]. Group 1: Technology Development - The visual prosthesis allows blind animal models to regain visible light vision and perceive infrared light, achieving "super vision" capabilities [1]. - The device utilizes a tellurium nanowire network (TeNWNs) that has the highest known photogenerated current density, enabling the widest spectral coverage for visual reconstruction [1]. - The prosthesis is thin and can directly replace degenerated photoreceptor cells, activating retinal neurons and transmitting signals through natural pathways without external devices [1]. Group 2: Experimental Validation - The effectiveness of the prosthesis was validated in non-human primates, specifically in crab-eating macaques, showing no adverse rejection reactions after six months of implantation [2]. - The research team is investigating the efficient coupling mechanism between the visual prosthesis and the retina, which is crucial for future clinical applications [2]. Group 3: Future Implications - The new generation of super-visual prosthesis technology has the potential to not only restore sight to the blind but also to expand human sensory perception beyond natural limits [2].
