TY  - JOUR
AB  - Capsule endoscopy has gained a lot of attentionin the medical field in the recent past as an effective way ofinvestigating unusual symptoms experienced in places such asesophagus, stomach, small intestine and colon. However, motioncontrol of the capsule endoscope is challenging and often requiresa power source and miniature actuators. To address these issues,we present a novel origami inspired structure as an attachmentto the capsule endoscope. The proposed origami structure utilizesthe wave generated by peristalsis of the intestine to move itforward and backward. When the origami structure is folded, thecapsule endoscope is propelled forward by intestinal peristalsis.When the origami structure is unfolded, the intestinal peristalsissqueezes the origami structure to drive the capsule endoscope tomove in the opposite direction. Therefore, folding and unfoldingof the proposed origami structure would allow to control themovement direction of the capsule endoscope. In this paper, wepresent the design, simulations and experimental validation ofthe proposed origami structure.
