How far away could be an artificial brain? Perhaps a very long way still, but a working analogue to the essential element of the brain’s networks, the synapse, appears closer at hand now. That’s because a device that draws inspiration from batteries now appears surprisingly well suited to run artificial…

The Device That Changed Everything

I was roaming around the IEEE Spectrum office a couple of months ago, looking at the display cases the IEEE History Center has installed in the corridor that runs along the conference rooms at 3 Park. They feature photos of illustrious engineers, plaques for IEEE milestones, and a handful of…

Robot Learns Human Trick for Not Falling Over

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. Humanoid robots are a lot more capable than they used to be, but for most of them, falling over is still borderline catastrophic. Understandably, the focus has been on getting humanoid robots to succeed…

On 16 December 1947, after months of work and refinement, the Bell Labs physicists John Bardeen and Walter Brattain completed their critical experiment proving the effectiveness of the point-contact transistor. Six months later, Bell Labs gave a demonstration to officials from the U.S. military, who chose not to classify the…

Liquid Metal Stretchy Circuits, Built With Sound

A team in Korea has used sound waves to connect tiny droplets of liquid metals inside a polymer casing. The novel technique is a way to make tough, highly conductive circuits that can be flexed and stretched to five times their original size.Making stretchable electronics for skin-based sensors and implantable…

"SuperGPS" Accurate to 10 Centimeters or Better

Modern life now often depends on GPS(short for Global Positioning System), but it can err on the order of meters in cities. Now a new study from a team of Dutch researchers reveals a terrestrial positioning system based on existing telecommunications networks can deliver geolocation info accurate to within 10…

This is a guest post in recognition of the 75th anniversary of the invention of the transistor. It is adapted from an essay in the July 2022 IEEE Electron Device Society Newsletter. The views expressed here are solely those of the author and do not represent positions of IEEE Spectrum…

The Transistor at 75

29 Νοεμβρίου 2022 by paulkokos

paulkokos

Seventy-five years is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles…

A Diamond "Blanket" Can Cool the Transistors Needed for 6G

28 Νοεμβρίου 2022 by paulkokos

paulkokos

High-power radio-frequency electronics are a hot commodity, both figuratively and literally. The transistors needed to amplify 5G and future 6G signals are struggling to handle the thermal load, causing a bottleneck in development. Engineers in the United States and England have teamed up to demonstrate a promising solution—swaddling individual transistors…

The Ultimate Transistor Timeline

27 Νοεμβρίου 2022 by paulkokos

paulkokos

Even as the initial sales receipts for the first transistors to hit the market were being tallied up in 1948, the next generation of transistors had already been invented (see “The First Transistor and How it Worked.”) Since then, engineers have reinvented the transistor over and over again, raiding condensed-matter…
