A generic approach for producing various protrusive shapes on different size scales using shape-memory polymer

We demonstrate a generic approach for producing different shaped and sized protrusive features using shape-memory polymer (SMP). Utilizing the large recoverable strain in the SMP, and depending on the pre-straining of the SMP, shape of the indenter, temperature during indenting and the depth of polishing, we show that a variety of features of different sizes can be easily obtained.
