The incorporation of electronics onto curved surfaces promises to bring new levels of intelligence to the ergonomic, aesthetic, aerodynamic, and optical surfaces that are ever-present in our lives. However, since many of these surfaces have two-dimensional (i.e. non-developable) curvature, they cannot be formed from the deformation of a flat non-stretchable sheet. This means that curved electronics cannot capitalize on the rapid technological advances taking place in the field of ultrathin electronics, since these devices, though ultra-flexible, are not stretchable. In this work, we present a shrink-based paradigm to apply such thin-film electronics to non-developable surfaces. When ultrathin electronics are attached to shrink film, they undergo


Steven Rich received a B.S. in Mechanical Engineering with a minor in Ecology and Evolutionary Biology from Rice University (Jones College). After graduation, he joined the Soft Machines Lab at Carnegie Mellon University, where his PhD work focused on phase-change and stiffness-switching materials in soft robotics. In 2019, he joined the Thin Film Devices Lab in RIKEN, Japan, where he has been studying ultrathin organic devices.
