Rubber-like Stretchable Energy Storage Device Fabricated with Laser Precision

Scientists use laser ablation technology to develop a deformable micro-supercapacitor. Professor Jin Kon Kim and Dr. Keon-Woo Kim from the Department of Chemical Engineering at Pohang University of Science and Technology (POSTECH), in collaboration with Dr. Chanwoo Yang and Researcher Seong Ju Park from the Korea Institute of Industrial Technology (KITECH), have achieved a significant breakthrough in developing a small-scale energy storage device capable of stretching, twisting, folding, and wrinkling. Their research has been published in the electronic engineering journal, npj Flexible Electronics.

The advent of wearable technology has brought with it a pressing need for energy storage solutions that can keep pace with the flexibility and stretchability of soft electronic devices.

Holographic Displays offer a Glimpse into an Immersive Future

A figure wearing holographic displays glasses, a chip on the leg of the eyeglasses beaming colored light onto the inside of the lens of the glasses.

Researchers at Princeton and Meta have created a tiny optical device that makes holographic images larger and clearer. Small enough to fit on a pair of eyeglasses, the device could enable a new kind of immersive virtual reality display. Illustration by Liz Sabol, photo by Nathan Matsuda

Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.

Holographic images have real depth because they are three dimensional, whereas monitors merely simulate depth on a 2D screen. Because we see in three dimensions, holographic images could be integrated seamlessly into our normal view of the everyday world.

The result is a virtual and augmented reality disp...

In what has become a familiar refrain when discussing artificial intelligence (AI)-enabled technologies, voice cloning makes possible beneficial advances in accessibility and creativity while also enabling increasingly sophisticated scams and deepfakes. To combat the potential negative impacts of voice cloning technology, the U.S. Federal Trade Commission (FTC) challenged researchers and technology experts to develop breakthrough ideas on preventing, monitoring and evaluating malicious voice cloning.

Ning Zhang, an assistant professor of computer science and engineering in the McKelvey School of Engineering at Washington University in St. Louis, was one of three winners of the FTC’s Voice Cloning Challenge announced April 8...

An international collaboration of researchers, led by Philip Walther at University of Vienna, have achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons using a novel resource-efficient platform. The work published in the journal Science Advances represents a notable advancement in optical quantum computing that paves the way for more scalable quantum technologies.

Interference among photons, a fundamental phenomenon in quantum optics, serves as a cornerstone of optical quantum computing.

It involves harnessing the properties of light, such as its wave-particle duality, to induce interference...
