Magnetic Knots Push Future Computing Toward 3D

Electrical, Electronics & Instrumentation, Metallurgy & Material Science

Knots in magnetic materials may provide a new direction for next-generation computing architectures to branch out into. To that end, researchers have now created a novel magnetic knot that looks like a tiny magnetized version of a cinnamon twist. And this same magnetic knot—embedded in a magnetic material a little…

Researchers Simplify Switching for Quantum Electronics

Electrical, Electronics & Instrumentation, Metallurgy & Material Science

A quantum cousin of the Hall effect could open the door to energy-efficient electronics, better sensors, and more-powerful quantum computers. Researchers have now broken a key barrier to its practical application by controlling the phenomenon electrically, rather than magnetically, for the first time. The Hall effect, discovered by physicist Edwin…

How online resources can support and simplify the design process

Electrical, Electronics & Instrumentation

Calculators Even with application circuits and reference designs available from many manufacturers, calculations remain a large part of a designer’s workload. Some may be simple, such as implementing Ohm’s law, while others are more complex, especially those relating to analogue design techniques such as filters, power systems and RF projects.…

Britons throw away nearly half a billion ‘fast tech’ items annually, research shows

Electrical, Electronics & Instrumentation

According to Material Focus, around 471 million ‘fast tech’ items were binned in the past year, with an average cost of around £4 per item. But while many of the items are perceived to be disposable, even low-cost electricals contain precious materials such as gold, aluminium and lithium, which should…

AI designs new robot from scratch in seconds

Electrical, Electronics & Instrumentation

The team tested the system by giving it a simple prompt: “Design a robot that can walk across a flat surface.” The computer started with a block about the size of a bar of soap. Knowing it was unable to walk, as instructed, the AI began making iterations of the…
