The Growing Materials Challenge


By Katherine Derbyshire & Ed Sperling Materials have emerged as a growing challenge across the semiconductor supply chain, as chips continue to scale, or as they are utilized in new devices such as sensors for AI or machine learning systems. Engineered materials are no longer optional at advanced nodes. They are now a requirement, and the amount of new material content in chips contin... » read more

Electrical twisted yarn The U.S. Air Force Research Laboratory (AFRL), the University of Texas at Dallas and Hanyan University in South Korea have developed a twisted yarn technology that can be used to generate or harvest electrical energy. The technology, dubbed “twistron” yarn, incorporates twisted bundles of tiny coiled carbon nanotubes. The nanotube-based twistron yarn works in con... » read more

3D printed military drones The U.S. Army Research Laboratory has begun testing 3D printed drones for use in on-demand military missions. The technology, called the On-Demand Small Unmanned Aircraft System (ODSUAS), enables a soldier to input the mission requirements in software. Then, a 3D printer devises the optimal configuration for an unmanned aerial vehicle. And it’s printed and deliv... » read more

Molybdenum disulfide memristors Researchers at Michigan Technological University constructed an ideal memristor based on molybdenum disulfide nanosheets. "Different from an electrical resistor that has a fixed resistance, a memristor possesses a voltage-dependent resistance," said Yun Hang Hu, professor of materials science and engineering at MTU, adding that a material's electric propert... » read more
