In the four decades since Sputnik, one rocket after another has punched through the skies above Baikonur Cosmodrome. But in the years following the collapse of the Soviet Union in December 1991, it looked as though Baikonur and the rest of the former Soviet space industry might pass into history, too.

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

Gallium nitride transistors have struggled to handle the thermal load of high-frequency electronics

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 in a blanket of thermally conductive diamond to keep them cool.

“Thermal issues are currently one of the biggest bottlenecks that are plaguing any kind of microelectronics,” says team lead Srabanti Chowdhury, professor of electrical engineering at Stanford University. “We asked ourselves ‘can we perform device cooling at the very material level without paying a penalty in electrical performance?’”

More than 100 years after the technology was first developed, the electrocardiogram (ECG) remains the gold standard for measuring the electrical activity of the heart. However, an ECG currently requires electrodes to be attached on a person’s skin. Even the latest consumer technologies like the Apple Watch require a user seeking an ECG to touch a finger to the device’s protruding “digital crown,” forming a circuit across the user’s body, thereby enabling electrical signals across the heart to be measured.

However, researchers in China have reported the invention of a novel ECG technology that uses millimeter-wave radar and AI to infer an ECG signal, making the system completely contactless. Should the researchers’ initial promising results bear out, the millimeter-wave tech could inspire new applications based on a reliable and uninterrupted stream of heart health data.
