Research Abstract

A traveling small capsule has been developed. The capsule has a smooth outer surface and is driven by inertia force and friction force. Measuring only 7 mm in diameter and 12 mm in length, it is sufficiently small to be placed in the human gullet or intestines. The capsule contains a small magnet and a coil, and an electric pulse drives the magnet to move the capsule. To investigate the feasibility of our traveling capsule, we did the theoretical analysis and the computer simulation using a simple model. We performed an experimental investigation on making our capsule travel on a plastic plate. We also showed that it can travel on the surface of a pig' s intestine. Our capsule may be useful for medical treatments such as inspection, drug delivery and operation.
