Wirelessly charging electric cars as they drive
Wirelessly charging electric cars as they drive
Engineers have demonstrated a practical way to use magnetism to transmit electricity wirelessly to recharge electric cars, robots or even drones. The technology could be scaled up to power electric cars as they drive over highways, robots on factory floors and drones hovering over rooftops. Stanford engineers have taken a big step toward making it practical for electric cars to recharge as they speed along futuristic highways built to "refuel" vehicles wirelessly.

Researchers solve ’link discovery’ problem for terahertz data networks
Leaky waveguide could help devices find one another on future, high-speed data networks By Kevin Stacey Special to Rice News When you open a laptop, a router can quickly locate it and connect it to the local Wi-Fi network. That ability, known as link discovery, is a basic element of any wireless network, and now a team of engineering researchers from Rice University and Brown University has developed a way to do that with terahertz radiation, the high-frequency waves that could one day make for ultrafast wireless data transmission.

Bose-Einstein condensate: magnetic particles behave repulsively
Bose-Einstein condensate: magnetic particles behave repulsively
Data transmission that works by means of magnetic waves instead of electric currents - for many scientists, this is the basis of future technologies that will make transmission faster and individual components smaller and more energy-efficient. Magnons, the particles of magnetism, serve as moving information carriers.

Fine-Tuning Magnetic Spin for Faster, Smaller Memory Devices
Fine-Tuning Magnetic Spin for Faster, Smaller Memory Devices
Unlike the magnetic materials used to make a typical memory device, antiferromagnets won't stick to your fridge. That's because the magnetic spins in antiferromagnets are oppositely aligned and cancel each other out. Scientists have long theorized that antiferromagnets have potential as materials for ultrafast stable memories.

Energy-harvesting design aims to turn Wi-Fi signals into usable power
Energy-harvesting design aims to turn Wi-Fi signals into usable power
Device for harnessing terahertz radiation might enable self-powering implants, cellphones, other portable electronics. Any device that sends out a Wi-Fi signal also emits terahertz waves -electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as "T-rays," are also produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.

A nanoscale device that can see through walls
Researchers at EPFL have developed a nanodevice that operates more than 10 times faster than today's fastest transistors, and about 100 times faster than the transistors you have on your computers. This new device enables the generation of high-power terahertz waves. These waves, which are notoriously difficult to produce, are useful in a rich variety of applications ranging from imaging and sensing to high-speed wireless communications.

Novel method for easier scaling of quantum devices
Novel method for easier scaling of quantum devices
System "recruits" defects that usually cause disruptions, using them to instead carry out quantum operations. In an advance that may help researchers scale up quantum devices, an MIT team has developed a method to "recruit" neighboring quantum bits made of nanoscale defects in diamond, so that instead of causing disruptions they help carry out quantum operations.

Integrating electronics onto physical prototypes
In place of flat "breadboards," 3D-printed CurveBoards enable easier testing of circuit design on electronics products. The aim is to provide a faster, easier way to test circuit functions and user interactions with products such as smart devices and flexible electronics. Breadboards are rectangular boards with arrays of pinholes drilled into the surface.

Quakes, dust devils and midnight magnetic pulses: findings from a year on Mars
InSight's Imperial-designed instrument has revealed that Mars trembles more often, but also more mildly, than expected. Detecting hundreds of marsquakes on a planet 140 million miles from Earth, using sensors developed in the UK, is an important achievement. Amanda Solloway UK Science Minister An international team of scientists led by NASA created Mars InSight , the first mission to study the deep interior of Mars , to generate unprecedented data about the planet's inner structure.

Engineers mix and match materials to make new stretchy electronics
Next-generation devices made with new "peel and stack" method may include electronic chips worn on the skin. Because computer chips are rigid, the electronic devices that they power, such as our smartphones, laptops, watches, and televisions, are similarly inflexible. Now a process developed by MIT engineers may be the key to manufacturing flexible electronics with multiple functionalities in a cost-effective way.

In surprise breakthrough, scientists create quantum states in everyday electronics
After decades of miniaturization, the electronic components we've relied on for computers and modern technologies are now starting to reach fundamental limits. Faced with this challenge, engineers and scientists around the world are turning toward a radically new paradigm: quantum information technologies. Quantum technology, which harnesses the strange rules that govern particles at the atomic level, is normally thought of as much too delicate to coexist with the electronics we use every day in phones, laptops and cars.
