Paper is a lightweight, abundant, and bio-degradable material. In addition, paper affords rich physical interactions including folding, printing, and painting on its surface. In recent years, paper has become increasingly interesting as a material in new interface design including paper robots, paper power generators, electronic pop-up books, animated origami, foldable artifacts, and so on. While many of these paper systems require customized actuation mechanisms, a missing component for paper-based interfaces is a low-cost, easy to fabricate, flexible to customize, reversible, and electronically-controllable actuator that is embedded within the paper.
We present the design and exploration of a new electrical and reversible paper actuator printed by a FDM 3D printer. The actuator is composed of inexpensive materials, such as common paper and off-the-shelf thermoplastic printing filaments. The fabrication process is fast and straightforward, which requires a single layer printing with a desktop FDM printer. Our paper actuator can be easily embedded into everyday objects to enable new types of paper-based shape-changing interfaces that exhibit motion, transformation, and rich interactivities such as pop-up books, toys, origami robots, and lampshades.
Printed Paper Actuator is the project that achieves a low cost, reversible and electrical actuation and sensing method. This method that requires simple and easy fabrication steps enables our paper actuator to achieve different types of motion and even various electrical sensing abilities: touch sensing, slider, and self-bending-angle detection. We introduce a software tool that assists the design, simulation, and printing toolpath generation.
