Lithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their capacity decreases over time. Now, for the first time, a team has used a non-destructive method to observe how the […]

In a network, pairs of individual elements, or nodes, connect to each other; those connections can represent a sprawling system with myriad individual links. A hypergraph goes deeper: It gives researchers a way to model […]

The evolution of wireless communications and the miniaturization of electrical circuits have fundamentally reshaped our lives and the digital landscape. However, as we push toward higher-frequency communications in an increasingly connected world, engineers face growing […]

By infusing red oak with ferrihydrite using a simple, low-cost process, researchers strengthened the wood at the cellular level without adding weight or altering flexibility—offering a durable, eco-friendly alternative to steel and concrete. The treated […]

Researchers have created a light-powered soft robot that can carry loads through the air along established tracks, similar to cable cars or aerial trams. The soft robot operates autonomously, can climb slopes at angles of […]

A team of roboticists at Tsinghua University, working with a trio of colleagues from Beihang University, all in China, has designed a new type of microrobot that can continuously transform its shape and “lock” into […]

Many products in the modern world are in some way fabricated using computer numerical control (CNC) machines, which use computers to automate machine operations in manufacturing. While simple in concept, the ways to instruct these […]

Over the past decades, electronics engineers have developed a wide range of wearable devices that can be used to track some physiological processes and collect health or fitness-related data. These devices rely on miniature sensors […]

Combining two different kinds of signals could help engineers build prosthetic limbs that better reproduce natural movements, according to a new study from the University of California, Davis. The work, published April 10 in PLOS […]

Lithium-ion batteries have been a staple in device manufacturing for years, but the liquid electrolytes they rely on to function are quite unstable, leading to fire hazards and safety concerns. Now, researchers at Penn State […]
