(Phys.org) —A small team of researchers at Bell Labs in New Jersey has built a camera that has no lens. Instead, as they explain in their paper they've uploaded to the preprint server arXiv, the camera uses a LCD array, ...
London-based Bare Conductive Ltd. makes electrically conductive paint called Bare Paint. The substance allows the painting of "liquid wiring" on any surface. Except for skin, you can apply its paint on walls and assorted ...
(Phys.org) —A team of European researchers working at École polytechnique fédérale de Lausanne (EPFL) in Switzerland has created an artificial compound eye that is comparable to those in insects such as the fruit fly. ...
Their system uses simple, cheap detectors which have just a single pixel to sense light instead of the millions of pixels used in the imaging sensors of digital cameras.
