A simple, robust, biomimetic responsive surface based on controlled elastic instabilities using an array of microlens shells as a surface geometry is presented. The snap‐through transition is dictated by geometry, length‐scale, and materials properties, thus the transition time, triggering sensitivity, and magnitude change are highly tunable. Their potential use as a rapidly switchable optical device is illustrated.
