System Bits: June 18


Another win for aUToronto Photo credit: University of Toronto The University of Toronto’s student-led self-driving car team racked up its second consecutive victory last month at the annual AutoDrive Challenge in Ann Arbor, Mich. The three-year challenge goes out to North American universities, offering a Chevrolet Bolt electric vehicle to outfit with autonomous driving technology.... » read more

Power/Performance Bits: June 4


Flexible high-temp dielectric Researchers at Rice University, Georgia Institute of Technology, and Cornell University developed a new high-temperature dielectric nanocomposite for flexible electronics, energy storage, and electric devices that combines one-dimensional polymer nanofibers and two-dimensional boron nitride nanosheets. The polymer nanofibers act as a structural reinforcement, w... » read more

High-temp electronics Researchers at Purdue University, UC Santa Cruz, and Stanford developed a semiconducting plastic capable of operating at extreme temperatures. The new material, which combines both a semiconducting organic polymer and a conventional insulating organic polymer could reliably conduct electricity in up to 220 degrees Celsius (428 F). "One of the plastics transports the ch... » read more

Camera for object recognition Researchers from the University of Illinois at Urbana-Champaign developed a new camera that could improve object detection in vehicles. Inspired by the visual system of mantis shrimp, the camera detects the polarization of light and has a dynamic range about 10,000 times higher than today's commercial cameras. "In a recent crash involving a self-driving car, th... » read more

Cobalt Shortages Ahead


Rapid growth of electric vehicles is creating an enormous demand for cobalt, causing tight supply, high prices and supply chain issues for this critical material. Cobalt is a ferromagnetic metal and one of the key materials used in lithium-ion batteries for cell phones, notebook PCs, battery-electric cars and hybrids. It also is used in alloys and semiconductors. And while the IC industry co... » read more
