When metamaterials are arranged in a stretchable platform, their practical applications (e.g., reconfigurable optoelectronic devices and biological sensors) can be greatly extended. B. Min and co-workers take inspiration from the wrinkled structures of various bio-organisms to develop a generic strategy for reversibly stretchable metamaterials. The structural integrities of the wrinkled THz metamaterials described, remain intact after repeated stretching/relaxing, and the wrinkled metamaterial makes a mechanically reversible transition between artificial homogeneous and inhomogeneous broadenings
