Shape-shifting OLED panel: Dynamic smartphone display with integrated speaker technology unveiled

A research team has developed the world’s first smartphone-type OLED panel that can freely transform its shape while simultaneously functioning as a speaker—all without sacrificing its ultra-thin, flexible properties.

The study, led by POSTECH’s (Pohang University of Science and Technology) Professor Su Seok Choi from the Department of Electrical Engineering and conducted by Ph.D. candidates Jiyoon Park, Junhyuk Shin, Inpyo Hong, Sanghyun Han, and Dr. Seungmin Nam, was published in the March online edition of npj Flexible Electronics.

As the industry rapidly advances toward flexible technologies—bendable, foldable, rollable, and stretchable—most implementations still rely on mechanical structures such as hinges, sliders, or motorized arms. While these allow for shape adjustment, they also result in increased thickness, added weight, and limited form factor design. These drawbacks are particularly restrictive for smartphones and wearable electronics, where compactness and elegance are critical.

Those constantly distracted by their phone will just find other ways to procrastinate if it isn’t nearby, study suggests

A new study published in Frontiers in Computer Science investigated if placing smartphones just out of our reach while we’re at work influenced device use for activities not related to work.

“The study shows that putting the smartphone away may not be sufficient to reduce disruption and procrastination, or increase focus,” said the paper’s author Dr. Maxi Heitmayer, a researcher at the London School of Economics. “The problem is not rooted within the device itself, but in the habits and routines that we have developed with our devices.”

Advancing semiconductor devices for AI: Single transistor acts like neuron and synapse

Researchers from the National University of Singapore (NUS) have demonstrated that a single, standard silicon transistor, the fundamental building block of microchips used in computers, smartphones and almost every electronic system, can function like a biological neuron and synapse when operated in a specific, unconventional way.

Led by Associate Professor Mario Lanza from the Department of Materials Science and Engineering at the College of Design and Engineering, NUS, the research team’s work presents a highly scalable and energy-efficient solution for hardware-based (ANNs).

This brings —where chips could process information more efficiently, much like the —closer to reality. Their study was published in the journal Nature.

A lighter, smarter magnetoreceptive electronic skin

Imagine navigating a virtual reality with contact lenses or operating your smartphone underwater: This and more could soon be a reality thanks to innovative e-skins.

A research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has developed an that detects and precisely tracks magnetic fields with a single global sensor. This artificial skin is not only light, transparent and permeable, but also mimics the interactions of real skin and the brain, as the team reports in the journal Nature Communications.

Originally developed for robotics, e-skins imitate the properties of real skin. They can give robots a or replace lost senses in humans. Some can even detect chemical substances or magnetic fields. But the technology also has its limits. Highly functional e-skins are often impractical because they rely on extensive electronics and large batteries.

Scientists Just Built a Battery That Never Needs Charging

Imagine never charging your phone again or having a pacemaker that lasts a lifetime. Scientists are developing tiny nuclear batteries powered by radiocarbon, a safe and abundant by-product of nuclear plants.

Unlike lithium-ion batteries, which degrade over time and harm the environment, these new designs use beta radiation to trigger an electron avalanche and generate electricity. The team’s latest prototype vastly improved efficiency, and though challenges remain, the technology could one day make nuclear power as accessible as your pocket device.

The Problem with Current Batteries.

A safe nuclear battery that could last a lifetime

Sometimes cell phones die sooner than expected or electric vehicles don’t have enough charge to reach their destination. The rechargeable lithium-ion (Li-ion) batteries in these and other devices typically last hours or days between charging. However, with repeated use, batteries degrade and need to be recharged more frequently.

Scientists Develop “Super Sapphire” That Resists Scratches, Glare, Fog, and More

New sapphire nanostructures created at UT Austin repel dust, glare, and fog while staying durable. Inspired by nature, these surfaces could be used in electronics, optics, space, and defense, and are being developed for real-world applications. Imagine a phone screen that stays flawless no matter

The Futurist Who Predicted the iPhone and Internet Now Claims That Immortality Could Be Reached in “5 Years” Time

A visionary who predicted the internet and smartphones is now making an even bolder claim about the future of humanity. Revolutionary technologies could soon make immortality a reality.

Keeping Japanese Children Safe in Cyberspace: Weighing the Roles of Government, Business, and Family

The use of smartphones in Japan is extending to younger and younger children, raising serious concerns about the dangers of social media. An online safety expert provides a snapshot of Japanese teens’ use of current platforms and considers the options for protecting children from cyberbullying, exploitation, and toxic content.

Cutting-edge experiments reveal ‘hidden’ details in transforming material with implications for faster microelectronics

Phase changes are central to the world around us. Probably the most familiar example is when ice melts into water or water boils into steam, but phase changes also underlie heating systems and even digital memory, such as that used in smartphones.

Triggered by or electricity, some materials can switch between two different phases that represent binary code 0s and 1s to store information. Understanding how a material transforms from one state or phase to another is key to tailoring materials with specific properties that could, for instance, increase switching speed or operate at lower energy costs.

Yet researchers have never been able to directly visualize how these transformations unfold in real time. We often assume materials are perfect and look the same everywhere, but “part of the challenge is that these processes are often heterogeneous, where different parts of the material change in different ways, and involve many different length scales and timescales,” said Aaron Lindenberg, co-author and SLAC and Stanford University professor.
