 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 electronics. Oxide-based devices could also find use in power electronics and communication technology, redu...

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 superior to, the photovoltaic effect commonly found in solar cells. Solar power is considered a key t...

 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 that a pulse oximeter -- a medical device typically placed on a fingertip that uses infrared and lig...

Until now, the high-capacity, fast-charging energy storage devices have been limited by the composition of their electrodes -- the connections responsible for ma...

 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 voltage. And once the material is bent, it holds its shape - even after the voltage is removed. As ...
