The adhesive mechanism to flexible surface is more and more important for a medical electrode, the future minute medical machine which moves and inspects in stomach, and so on. In order to investigate the superior adhesive mechanism, the authors take up the suction electrode for electrocardiograph which is now desired to improve and also can be the base of mechanism with its simple structure. The chest suction electrode is constructed with a steel cup and a rubber sphere and can adhere to skin with the suction pressure. But there are many different types of skin, so the suction time varies. If the electrode is fallen off while electrocardiogram running, the inspection becomes impossible. Moreover it is a problem that the skin is engorged and damaged by the suction pressure. To overcome such problems, the paper makes experimental investigations on the influence of the shape and rubber elasticity of the electrode and the elastic characteristics of skin. Based on the results, the authors propose the "flexible over-hemisphere electrode", and confirm the validity with experiments. The newly proposed electrode could adhere to skin for far longer time than present ones with less suction pressure. Also, the paper tries to analyze the performance with a simple model.
