Being born in Munich, growing up in Canada and the United States and now living in Hong Kong, German photographer Michael Wolf is fascinated by his surroundings and contemporary life in big cities. After capturing the architectural density of his adoptive hometown and claustrophobic images of public transport passengers, Wolf now offers a different view on Paris. His series „paris roof tops“ avoids all the clichés connected to the „city of lights“ and instead features geometric patterns and muted colours in the distinctive looks of the French capital’s buildings.
Graphene-Based Artificial Retina Sensor Being Developed
Researchers at Germany’s Technical University of Munich are developing graphene sensors like the ones depicted above to serve as artificial retinas. The atom-thick sheet of linked carbon atoms is being used because it is thin, flexible, stronger than steel, transparent and electrically conductive.
TUM physicists think that all of these characteristics and graphene’s compatibility with the body make it a strong contender to serve as the interface between a retinal prosthetic that converts light to electric impulses and the optic nerve. A graphene-based sensor could help blind people with healthy nerve tissue see, they say.
