Wireless communication's crystal ball
By now, wireless connections like Wi-Fi and Bluetooth are just as commonplace in industry. Yet systems often interfere with one another as data is being exchanged. Now, "Awair" will not only detect available ...
World's first demonstration of power transfer from wheels to power an electric car
Electric vehicles (EV) have ten times higher energy performance than automobiles powered by gasoline-based engines. However, they are not yet popular with drivers due to the need to store large batteries onboard. Now, Takashi ...
A low-cost, finger-nail sized radar
European researchers have squeezed radar technology into a low-cost fingernail-sized chip package that promises to lead to a new range of distance and motion sensing applications. The novel device could have important uses ...
New technique excites atoms and molecules using pulsed laser
The best method to obtain the most precise information on the inner structure of atoms and molecules is to excite them by means of resonant laser light. Unfortunately, just this laser light (above a certain ...
Small bats squeak at higher pitch to focus better, study reports
Small bats have to emit higher-pitched squeaks than their bigger cousins for their sonar navigation systems to work equally well, scientists said Wednesday.
One size cloaks all
A metamaterial invisibility cloak that can adapt to hide different sized objects is demonstrated by in Nature Communications this week. The findings represent a useful advance for more practical applications of metamaterial cloaki ...
