Researchers at the Georgia Institute of Technology have discovered a new, helical, zinc-oxide nanostructure that could be very useful to engineers working on nanoscale devices that rely on electromechanical coupling, such as sensors, resonators and transducers. Although the nanostructure looks like a spring, it is actually rigid, rather than elastic, and holds its shape even when it is isolated. They exist in both right and left handed versions. Production tends to split 50-50 between the two.
