Nanotechnology takes steps towards artificial retinas

Sensory substitution with flexible electronics is one of the intriguing fields of research that takes place in nanotechnology labs around the world. In line with this focus on human senses, in the future artificial retinas integrated with the human body may not only repair damaged vision but also expand it to see a wider range wavelengths (e.g. ultraviolet light). Researchers now have demonstrated a new self-powered brain-linked vision electronic skin (e-skin) for mimicking the human retina. The general idea of our device design of brain-linked vision electronic skin is constructing an integrated flexible system including photodetector array, information analyzer, signal transmitter, and electricity power unit.
