 E-Mail Credit: RMIT University A new study, out this week, could pave the way to revolutionary, transparent electronics. Such see-through devices could potentially be integrated in glass, in flexible displays and in smart contact lenses, bringing to life futuristic devices that seem like the product of science fiction. For several decades, researchers have sought a new class of electronics based on semiconducting oxides, whose optical transparency could enable these fully-transparent electron...

For the first time, researchers have discovered a way to obtain polarity and photovoltaic behavior from certain nonphotovoltaic, atomically flat (2D) materials. The key lies in the special way in which the materials are arranged. The resulting effect is different from, and potentially su...

 E-Mail Achuta Kadambi, an assistant professor at the UCLA Samueli School of Engineering, published a column in the journal Science about how medical devices can be fundamentally biased -- not just in dataset representation as has been widely reported, but from a deeper root: the laws of physics. Kadambi described how the inherent physics behind medical devices could vary across race and gender. He cited several examples of potential physics-based bias. For example, recent research has shown ...

Until now, the high-capacity, fast-charging energy storage de...

 E-Mail ITHACA, N.Y. - If you want to build a fully functional nanosized robot, you need to incorporate a host of capabilities, from complicated electronic circuits and photovoltaics to sensors and antennas. But just as importantly, if you want your robot to move, you need it to be able to bend. Cornell researchers have created micron-sized shape memory actuators that enable atomically thin two-dimensional materials to fold themselves into 3D configurations. All they require is a quick jolt of...

Credit: Christian Fleury (INRS) Finding the best materials for tomorrows electronics is the goal of Professor Emanuele Orgiu of the Institut national de la recherche scientifique (INRS). Among the materials in which Professor Orgiu is interested, some are made of molecules that can conduct electricity. He has demonstrated the role played by molecular vibrations on electron conductivity on crystals of such materials. This finding is important for applications of these molecular materials in elec...

The hummingbird is named after its pleasant humming sound when it hovers in front of flowers to feed. But only now has it become clear how the wing generates the hummingbirds namesake sound when it is beating rapidly at 40 beats per second. Researchers from Eindhoven University of Technology, Sorama, a TU/e spin-off co...

Wearable devices and biosensors are prone to heating up, especially under sunlight. However, conventional radiative coolers contain metallic materials, which limits wireless communications. Now scientists from Korea and the USA have developed a new type of radiative cooler using perforated polymers that keep the gadgets cool and fully functional under heat, paving the way for thermally protected wearable devices for health monitoring.
