When you think of robotics, you likely think of something rigid, heavy, and built for a specific purpose. New “Robotic Skins” technology developed by Yale researchers flips that notion on its head, allowing users to animate the inanimate and turn everyday objects into robots.

Developed in the lab of Rebecca Kramer-Bottiglio, assistant professor of mechanical engineering & materials science, robotic skins enable users to design their own robotic systems. Although the skins are designed with no specific task in mind, Kramer-Bottiglio said, they could be used for everything from search-and-rescue robots to wearable technologies...

Worldwide efforts to make sodium-ion batteries just as functional as lithium-ion batteries have long since controlled sodium’s tendency to explode, but not yet resolved how to prevent sodium-ions from ‘getting lost’ during the first few times a battery charges and discharges. Now, researchers made a sodium powder version that fixes this problem and holds a charge properly.

Most of today’s batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate...

Their ultrathin, conductive, and transparent hybrid NMs can be applied to the fabrication of skin-attachable NM loudspeakers and voice-recognition microphones, which would be unobtrusive in appearance due to their excellent transparency and conformal contact capability.

An international team, affiliated with UNIST has presented an innovative wearable technology that will turn your skin into a loudspeaker. This breakthrough has been led by Professor Hyunhyub Ko in the School of Energy and Chemical Engineering at UNIST. Created in part to help the hearing and speech impaired, the new technology can be further explored for various potential applications, such as wearable IoT sensors and conformal health care devices.

In the study, the research team has developed ultrathin, transp...

In this artist’s conception of the Nebraska experiment, the white orbs represent two laser pulses, with plasma waves in their wakes. The waves interfere with one another after the laser pulses cross, and electrons ride the wakefield waves to higher energy.

Force of light boosts electrons close to speed of light. In a recent experiment at the University of Nebraska-Lincoln, plasma electrons in the paths of intense laser light pulses were almost instantly accelerated close to the speed of light.

Physics professor Donald Umstadter, who led the research, said the new application might aptly be called an “optical rocket” because of the tremendous amount of force that light exerted in the experiment...
