Univ. of Minnesota electrical engineering researchers have developed a unique nanoscale device that for the first time demonstrates mechanical transportation of light. The tiny device is just .7 micrometers by 50 micrometers and works almost like a seesaw. On each side of the “seesaw benches,” researchers etched an array of holes, called photonic crystal cavities. These cavities capture photons that streamed from a nearby source.
Some smartphones are starting to incorporate 3-D gesture sensing based on cameras, but cameras consume significant battery power and require a clear view of the user’s hands. Univ. of Washington engineers have developed a new form of low-power wireless sensing technology that could soon contribute to gesture control by letting users “train” their smartphones to recognize and respond to specific hand gestures near the phone.
Washington State Univ. professor Rich Lamb has figured out a dramatically easier and more cost-effective way to do research on science curriculum in the classroom, and it could include playing video games. Called “computational modeling,” it involves a computer “learning” student behavior and then “thinking” as students would. Lamb, who teaches science education, says the process could revolutionize the way educational research is done.
Building on previous research that twisted light to send data at unheard-of speeds, scientists at the Univ. of Southern California (USC) have developed a similar technique with radio waves, reaching high speeds without some of the hassles that can go with optical systems.
