| Research Abstract |
We have developed a traveling small capsule, which has smooth outer surface and is driven by the inertia force and friction force. It is small enough, only 7 mm in diameter and 12 mm long, it can be put in the human gullet or intestines. The capsule contains a small magnet and a coil, and electric pulse drives the magnet to move the capsule. To investigate the feasibility of our traveling capsule, we did the theoretical analysis using a simple model. Separating the phenomena into four steps, we obtained fundamental equations and made the motion clear. We did the experimental investigation that our capsule can travel on a plastic material, which has similar elasticity characteristics to living body, and it can also travel on pig intestine surface. We have measured the temperature of the capsule during the move to evaluate safetiness to human body. Using calculated results, we have arranged new input signal pattern for the capsule and succeeded to move the capsule about twice as fast as the former one. Our capsule is supposed to be useful for medical treatment as inspection, drug delivery or operation.
