Make an Origami Circuit Board
Summary
IEEE Spectrum covers a hands-on approach to creating origami circuit boards by folding a paper-like substrate impregnated with conductive liquid metal to form traces. The article introduces LiqMetCraft, a toolkit and browser-based design software that guides users through three versions of the project (donut-inspired, origami, and 3D models) and discusses conductivity, assembly, and potential future enhancements like embedded switches and potentiometers. It highlights low material costs and educational applications for teaching electronics and fabrication skills.
