FoamSense: Design of Three Dimensional Soft Sensors with Porous Materials
summary
FoamSense measures compressed, bent, twisted and sheared states by dip-coating porous foam with conductive ink and wiring the surface with conductive glue; resistance falls steeply at small deformation as pores close and becomes roughly linear after pores collapse. Prototype forms include cut sponge sensors in a doll arm, a neck pillow controller and a sponge “sword,” and a 3D-printed porous silicone with anisotropic holes that tunes directional response; current limits are ~1–2 cm spatial resolution, sensor variability and material fatigue requiring calibration or ML.
