We have developed a traveling small capsule, which has a smooth outer surface and is driven by vibration. Measuring only 11 mm in diameter and 25 mm in length, it is sufficiently small to be placed in the human gullet or intestines. Although the capsule does not have wheels nor legs, it can travel utilizing vibration. For these reasons, there is nothing protruding to harm the soft tissue of intestine. The capsule contains a small magnet, a coil, batteries and a circuit, and an electric pulse drives the coil to move the capsule. We did the experimental investigation that our capsule can travel in a plastic pipe and it can also travel on pig intestine surface. We also have developed liquid medicine dispenser that can be put inside the capsule. Our capsule may be useful for medical treatments such as inspection and drug delivery.
