초록
Recently, capsule endoscope was developed to observe small intestine in human body. However, the capsule does nothave any locomotive ability, which reduces the benefit of the capsule endoscope. Many researches have done to givelocomotion to the capsule, still it consumes too much power to generate the motion by smal batery. One of the movingmethod is electrical stimulus that consumes les power than many methods. The electrical stimulus method causesby electrical stimulus, however the relationship between electrical stimulus at the mucous and contraction force in thesmal intestine is not reported, yet. In this paper, the mucous in the smal intestine was stimulated, and measured thecontraction force in the small intestine is shown. The result shows, the relationship between electrical stimulus parameters(voltage, duration) and contraction force. Also, equation between electrical stimulus parameters and contraction force isroughly induced.
Abstract

One of the movingmethod is electrical stimulus that consumes les power than many methods. The electrical stimulus method causesby electrical stimulus, however the relationship between electrical stimulus at the mucous and contraction force in thesmal intestine is not reported, yet. In this paper, the mucous in the smal intestine was stimulated, and measured thecontraction force in the small intestine is shown. The result shows, the relationship between electrical stimulus parameters(voltage, duration) and contraction force.
