ElectriPop: Low-Cost, Shape-Changing Displays Using Electrostatically Inflated Mylar Sheets

Abstract

We describe how sheets of metalized mylar can be cut and then "inflated"into complex 3D forms with electrostatic charge for use in digitally-controlled, shape-changing displays. This is achieved by placing and nesting various cuts, slits and holes such that mylar elements repel from one another to reach an equilibrium state. Importantly, our technique is compatible with industrial and hobbyist cutting processes, from die and laser cutting to handheld exacto-knives and scissors. Given that mylar film costs
