Microelectromechanical systems (MEMS) are tiny components etched from silicon. Production is extremely complex, sometimes with hundreds of steps, each with dozens of parameters. One European project has developed software ...
A new theory developed at MIT could lead to "smart" optical microchips that adapt to different wavelengths of light, potentially advancing telecommunications, spectroscopy and remote sensing.
A tiny sensor that can detect magnetic field changes as small as 70 femtoteslas-equivalent to the brain waves of a person daydreaming-has been demonstrated at the National Institute of Standards and Technology (NIST). The ...
St Andrews scientists have discovered a new way of levitating tiny objects - paving the way for future applications in nanotechnology.
University of California, Riverside nanotechnologists have succeeded in controlling the color of very small particles of iron oxide suspended in water simply by applying an external magnetic field to the solution. The discovery ...
Imagine a mechanical Pelé or David Beckham six times smaller than an amoeba playing with a “soccer ball” no wider than a human hair on a field that can fit on a grain of rice. Purely science fiction? Not anymore.
Researchers have designed a millimeter-sized sensor that has many of the tactile abilities of a human finger: it can sense the magnitude and the position of an applied force, slippage of a grasping tool, and the softness ...
University of Utah physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers ...
As many homeowners know, when stacking firewood, pieces should be placed close enough to permit passage of a mouse, but not of a cat chasing the mouse.
The single-celled Spirostomum is a tiny brown worm that can contract its 500-micrometer-long body to 25% of its length in a millisecond, making this protozoan the fastest-contracting microorganism known. Scientists think ...
