Washington: An international team of researchers has developed a simple new fabrication technique mimicking the action of a children's pop-up book to transform two-dimensional micro- and nano-structures into more complex 3D shapes. Using a variety of advanced materials, including silicon, the researchers said they produced more than 40 different geometric designs, including shapes resembling a peacock, flower, starburst, table, basket, tent and starfish.

"In just one shot you get your structure," Xinhua news agency quoted co-corresponding author Huang Yonggang, professor of the Northwestern University, as saying in a statement. "We first fabricate a two-dimensional structure on a stretched elastic material. Then we release the tension, and up pops a...
