S1280CS ShapeTape and S1680 High-Speed ShapeTape
A light weight, wearable, flexible ribbon that uses its own software, ShapeWare to create a 3D computer image and data set of its shape in real time, based on bend and twist information from an array of fiber optic sensors along its length. It follows human arm, leg, back, and neck movements for motion capture, virtual reality, biomedical, gaming, and robotic control applications. It is also used for crash testing, computer-aided design, and automotive interior design.
