Deborah Chung, Ph.D., professor of mechanical and aerospace engineering at the University at Buffalo (Buffalo, NY), discovered semiconducting behavior from an unusual source: a carbon composite. Her work endows structural materials with electronic capabilities without computer chips or electrical leads. Chung says, "We can use the structural material itself as the electronics." Made from carbon fibers embedded in a polymer matrix, the material would be easier and less expensive to fabricate than traditional silicon-based electronics, says Chung. According to the researcher, the process spreads electronic capabilities over a large surface area, therefore heat dissipation--now one of the biggest technological challenges facing electronic packaging--would no longer be a problem. Chung's work was presented at the International Symposium on Smart Structures and Materials in San Diego on March 4. Call (716) 645-3811.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
Anyone who’s ever moved files from a hard drive to a computer has sat patiently waiting for the transfer to complete. But what if this process could be done wirelessly, without having to connect devices with cables, and in seconds?
