We present Self-powered Paper Interfaces (SPIN) combining folding paper creases with triboelectric nanogenerator (TENG). Embedding TENG into paper creases, we developed a design editor and set of fabrication techniques to create paper-based interfaces that power sensors and actuators. Our SPIN design editor enables users to design their own crease pattern by changing parameters, embed power generating modules into the design, estimate total power generation, and export the files. Then following the fabrication instructions, users can cut and crease materials, and assemble them to build their own interfaces. We employ repetitive push-and-pull based embodied interactions with the mechanism of paper creases and demonstrate four application examples that show new expressive possibilities applying different scales of embodied interactions.
The Interactive Product Design Lab (IPDL) is a purpose-built lab designed to support both teaching and research by allowing students to investigate, explore, and experiment with an extensive array of new technologies. Central to this concept, the School of Industrial Design has placed a high priority on the need to foster and develop interdisciplinary, team-based collaboration with other educational and research units from across the campus, including the School of Interactive Computing, the School of Mechanical Engineering, the Graphics Visualization and Usability Lab (GVU), and the Center for Assistive Technology and Environmental Access (CATEA). The Interactive Product Design Lab was built in the summer of 2011 and opened in time for the 2011 fall semester.
