KiriInflate: Fabricating Cross-Scale Inflatables with Large-Magnitude Contraction and Tunable Str...
summary
KiriInflate presents a one-step fabrication using an off-the-shelf laser cutter + electrostatic PE film process that simultaneously cuts and heat-welds to produce ultra-narrow 0.125 mm seams and enable cross-scale inflatables from fingernail to body size. Structures achieve up to 83.5% contraction and tunable passive stretch by air pressure; experiment tables link geometry (width, thickness) to contraction and force, force is lower than McKibben but sufficient for an eyelid assist, game handle, lamps, and a parametric web tool for pattern generation.
