A new method uses optics to accelerate machine-learning computations on smart speakers and other low-power connected devices. The technique may enable self-driving cars to make decisions in realtime while only using a fraction of the energy that is currently demanded by their power-hungry on-board computers.

Drexel Materials science researchers demonstrate MXene polymer coating can block and absorb interference. A recent discovery by materials science researchers in Drexel University’s College of Engineering might one day prevent electronic devices and components from going haywire when they’re too close to one another. A special coating that they developed, using a type of two-dimensional material called MXene, has shown to be capable of absorbing and disbursing the electromagnetic fields that are the source of the problem.

Buzzing, feedback or static are the noticeable manifestation...

Distinguishing this intrigung material behavior at small scales could reduce energy demands for computing. As electronic devices become smaller and smaller, the materials that power them need to become thinner and thinner. Because of this, one of the key challenges scientists face in developing next-generation energy-efficient electronics is discovering materials that can maintain special electronic properties at an ultrathin size.

Advanced materials known as ferroelectrics present a promising solution to help lower the power consumed by the ultrasmall electronic devices found in cellphones and computers...

Discarded electronic devices, such as cellphones, are a fast-growing source of waste. One way to mitigate the problem could be to use components that are made with renewable resources and that are easy to dispose of responsibly. Now, researchers reporting in ACS Applied Materials & Interfaces have created a prototype circuit board that is made of a sheet paper with fully integrated electrical components, and that can be burned or left to degrade.

Most small electronic devices contain circuit boards that are made from glass fibers, resins and metal wiring...
