A new technique combines 3D printing with laser annealing to produce intricate conductive metallic...

A ubiquitous office and school supply has just gotten a technical upgrade. A team of researchers from the University of Washington, Disney Research and Carnegie Mellon University have given paper sensing abilities so that just like modern devices, items made from paper can respond to swipes and taps and connect to the digital world.

Engineers at Australia’s University of New South Wales have set a new world record for solar efficiency. Using normal sunlight without concentrators, they achieved 34.5 percent conversion efficiency, which is 44 percent better than the previous record.

A team of electrical engineering researchers placed a 2D semiconductor (MoS2) on top of an optical nanocavity. The structure improved the material’s absorption of light, so it could absorb 70 percent of a laser that was projected onto it. This approach could lead to more efficient and flexible electronics.

Engineers at Drexel University developed an app that uses augmented reality to demonstrate antenna performance. The BeamViewer app visualizes electromagnetic signals and demonstrates the difference between a standard antenna and a smart reconfigurable antenna, which adjusts its signals to find the best path.

Who is at fault when an autonomous vehicle crashes? Two drivers are blaming the Tesla's automated features for recent crashes. In both cases, Tesla disputes the claims.

Radio Frequency Identification (RFID) technology is an accurate and convenient method for asset management and inventory tracking, but it comes at a cost. Some researchers have focused on redesigning RFID tags to make them smaller and therefore cheaper, but now two electrical engineers working for Disney Research have developed RFID technology that eliminates the tags altogether. The new system uses the electromagnetic signals that gadgets already emit, which makes this method less expe

Engineers at NC State developed a new technique that makes RFID tags less expensive and 25 percent smaller than conventional versions. They shrunk the tags by eliminating the bulky hardware that is typically required in passive RFID systems for AC/DC conversion.

Researchers led by MIT postdoc Cui-Zu Chang has achieved the first zero-resistance edge state in a circuit. The circuit exhibits the quantum anomalous Hall effect, a property that allows it to transfer information. Superconductors have also achieved zero resistance, but they can only transfer electrical information.

Roads and sidewalks could soon be lit without electricity, using a new type of...
