Scientists have identified a method for improving the thermal conductivity of thin metal films in semiconductors using surface waves for the first time in the world.

The demand to shrink the size of semiconductors coupled with the problem of the heat generated at the hot spots of the devices not being effectively dispersed has negatively affected the reliability and durability of modern devices. Existing thermal management technologies have not been up to the task...

Recent advancements in the field of electronics have enabled the creation of smaller and increasingly sophisticated devices, including wearable technologies, biosensors, medical implants, and soft robots. Most of these technologies are based on stretchy materials with electronic properties.

While material scientists have already introduced a wide range of flexible materials that could be used to create electronics, many of these materials are fragile and can be easily damaged...

A team of researchers in the Penn State School of Electrical Engineering and Computer Science aims to enable health care and extended reality—which encompasses virtual, augmented and mixed reality—with their smart sensing ring, OmniRing.

The ring uses both inertial measurement unit (IMU) sensors, which can capture location, speed and rotation of the fingers, and photoplethysmography (PPG) sensors, which utilize an infrared light to measure volumetric changes in blood circulation...

An optical fiber about the thickness of a human hair can now carry the equivalent of more than 10 million fast home internet connections running at full capacity.

A team of Japanese, Australian, Dutch, and Italian researchers has set a new speed record for an industry standard optical fiber, achieving 1.7 Petabits over a 67km length of fiber. The fiber, which contains 19 cores that can each carry a signal, meets the global standards for fiber size, ensuring that it can be adopted without massive infrastructure change. And it uses less digital processing, greatly reducing the power required per bit transmitted.

Macquarie University researchers supported the invention by developing a 3D laser-printed glass chip that allows low loss acce...
