Building on their prior work with stetchable silicon, the research grop of Prof. John Rogers has now introduced "wavy" silicon. By applying sheets of Si to a stretched rubber sheet, the silicon can be buckled into previously unseen geometries by releasing the tension on the underlying rubber. The resulting herringbone pattern's waves and zigzags allow the silicon to strech in two directions.

The work is being highlighted in the Nano Letters Articles ASAP website while awaiting publication, and is already being featured in MIT's Technology Review.
