Like the signals it emits, the radio may soon disappear from sight.
University of Florida electrical engineers have installed a radio antenna less than one-tenth of an inch long on a computer chip and demonstrated that it can send and receive signals across a room. The achievement is another step in the teams continuing efforts to build an "ultrasmall radio chip" – a transceiver, processor and battery all placed on a chip not much larger than a pinhead – and one that could one day be used for applications ranging from detecting illegal border crossing to ensuring bridge and tunnel safety.
"This project is about building very small radios that are very hard to detect, both electrically and physically," said Ken O, a UF professor of electrical and computer engineering and one of six authors of an article reported in last months edition of Electrical and Electronics Engineering Electron Device Letters. "Since the antenna is usually the biggest part of the radio, this is a significant step."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
