Many micro-aerial vehicles can benefit from having compact and robust pre-deployment configurations that can later transform into larger and more capable forms. We demonstrate parylene-covered silicon frames that can be folded into origami-inspired aerodynamic shapes for structural applications in centimeter-scale aircraft. By changing the spacing between the frames, we can control the conformality of the parylene deposition, which determines the directionality of the fold (mountain or valley). We fabricated a foldable propeller from such polymer-coated frames and characterized its mass and thrust. [2020-0095]
