Power/Performance Bits: Sept. 5

Energy-harvesting yarn Researchers at the University of Texas at Dallas and Hanyang University in South Korea developed a carbon nanotube yarn that generates electricity when stretched or twisted. Possible applications for the so-called "twistron" yarns include harvesting energy from the motion of ocean waves or from temperature fluctuations. When sewn into a shirt, these yarns served as a sel... » read more

System Bits: Sept. 20

Improving Torque Sensing In an advance that could bring new types of sensors and studies in quantum mechanics, Purdue University researchers have levitated a tiny nanodiamond particle with a laser in a vacuum chamber, using the technique for the first time to detect and measure its torsional vibration. The team said the experiment represents a nanoscale version of the torsion balance used i... » read more
