Researchers in Professor Pedro Reis’s lab, in collaboration with a team from EPFL in Switzerland, have developed a rapid fabrication technique and a theory that accurately predicts the final thickness of a shell of a known material given the original rheological properties of the material and the geometry of the mold used for the coating. Inspired by the making of chocolate confections like hollow chocolate eggs and bonbons, the fabrication technique and theory may lead to application innovations for artificial vesicles, smart skins, and protective and packaging films on curved components.
