FlexiBend: Enabling Interactivity of Multi-Part, Deformable Fabrications Using ...
summary
A flexible, installable shape-sensing strip with a linear array of 16 strain gauges mounts into 3D-printed objects (NinjaFlex substrate) and reconstructs curvature at 45 FPS, yielding about 7 mm average joint error and under 2 cm endpoint error. A gear-locking case isolates segments so multiple widgets work simultaneously; a 3 cm slider reliably distinguishes eight positions. Prototypes include pressure analog buttons, dial and knob interfaces, a copper-tape variant for thinner boards, and low-power resistive readout suitable for future BLE wireless.
