eye-lens camera contact lens and monitoring your body for health purposes

220px-Sony_DSC-H2_01First watch the video below!

Cameras have long mimicked  the optics of the eye. Both collect and focus light with a convex outer lens. However, cameras have a shortcoming: They typically focus the image onto a flat surface. Whether this surface is covered with film or a digital sensor, distortion results from the projecting of light from a curved lens onto the flat 120px-Eye_Central_Heterochromia_crop_and_lightersurface. The insertion of additional lenses reduces the distortion, but this adds to camera weight and cost. Our eye with its hemispherical shape has no such problem.

ultra-small lab equipment based on Bladderworts roots

Bladderwort1 Bladderwort2One of the smallest traps in the world is inspiring physicists in studies of fluids. Bladderworts are a type of plant that grows in standing water or wet soil, and sometimes in very rough conditions. A unique aspect of this plant is its underwater roots which include many microscopic bladder-like traps. The trap looks like a small bubble and is covered with tiny hairs and “trap-doors.” The plants capture tadpoles, protozoa, or even water fleas, depending upon the species. When the unsuspecting victim approaches the trap-door, it suddenly opens, sucks in the creature, and then shuts again, all in less than one-thousandth of a second. Bladderworts are among the smallest carnivorous plants in the world.

ultra thin pipettes

Dog inspired drying machines

dogshakingPerhaps you have stood near a wet dog as it dries by shaking its fur. Watch out! An impressive amount of water is thrown off in all directions. The shaking technique for furry creatures including mice, dogs, and bears is studied by researchers at the Georgia Institute of Technology in Atlanta. They find that larger animals tend to move their bodies at a frequency of 4-5 shakes per second. Mice and rats move more rapidly, up to 27 shakes per second. Whatever the size, each creature begins the shaking process with its head and then the process moves along the body. Mathematical formulas have been established for the animal shaking process based on size, nature of the fur, water surface tension, and other variables. The animals apparently know these technical details by instinct.

Wild animals (macrosystem) show the same behavior like electrons (microsystem)

1024px-Cougar_closeup integrated-circuit-layoutThe search for a solution led McRae, now a biologist at the National Center for Ecological Analysis and Synthesis, to his past life as an electrical engineer. He had a hunch that the way animals travel through a landscape might be similar to how electricity moves across circuits. If that were the case, circuit theory would help explain how genes disperse.

Festo´s world of bionic solutions

festo bionicFesto has been working intensively on the topic of bionics since the early 90s. In 2006, the Bionic Learning Network was launched – an association of renowned universities, institutes and development companies. Since this time, Festo has been developing and supporting projects and test objects whose basic technical principles are derived from a wide variety of principles found in nature.

shoals of fish will offer their secret for windfarms

fishsoal windfarmWind turbines are the Colossus of the modern landscape, their blades sweeping circles more than a football field in diameter. Critics call them unsightly and say that the rotating blades clobber unsuspecting birds.

John Dabiri of Caltech found a solution underwater. He built an experimental wind farm — the Caltech Field Laboratory for Optimized Wind Energy (FLOWE) — in which the location of turbines relative to each other takes advantage of the air flow among them.

Self healing materials

genMany processes in organisms based on the self-organization of biological components. For materials scientists, such substances are a dream: you react autonomously to their environment and can adapt to this different conditions. At the U.S. MIT researchers aim to produce such wonders molecules artificially.

Manta Ray goes beyond air

manta_ray_2Air-ray, modelled on the manta ray, is a remote-controlled hybrid construction consisting of a helium-filled ballonet and a beating wing drive. Its lightweight design enables it to “swim” in the sea of air using the lift from the helium in a similar way to the manta ray in watemanta_rayr.

A team of mechanical and civil engineers at Loughborough University, UK, hopes to construct buildings that can create comfortable living conditions by extending our use of renewable forms of energy. How so? By unlocking a few of the mysteries found in the termite mounds on the plains of Namibia, Africa.
