Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Micro‐optical elements with micro‐ and nanoscale surface features prepared from an optically transparent shape‐memory elastomer via replica molding at high precision are reported by Tao Xie, John A. Rogers, and co‐workers <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">on page 3299</ext-link>. Through shape‐memory programming, the surface features and corresponding optical functions can be manipulated both globally and locally in a controlled manner. The image illustrates that a flattened microlens array loses the capability to focus light and only those completely recovered microlenses (coupled with a circular indium tin oxide heater) are able to project the letter "A" after thermal activating. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg26mdkc4w" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
