Shape-Measurable Device Based on Origami Structure with Single Walled Carbon Nanotube Strain Sensor

This paper describes a shape-measurable sheet device using origami structures with single-walled carbon nanotubes (SWCNTs) strain sensors. Previous measurement systems tended to be unable to recognize the stretching and bending of the object surface as different deformation. Here, we propose a shape-measurable device based on origami structure that can distinguish the stretching and the bending appropriately using only strain sensors. We fabricated the strain sensors using SWCNTs that was formed a 5-7 nm thin film on a substrate. We experimented that our origami sheet device could recognize the bending and stretching information separately by attaching the device to cylinders. We are convinced that the origami sheet system could contribute to the observation of complex deformations in various fields.
