Development of a peristaltic pump based on bowel peristalsis using for artificial rubber muscle

The global water shortage has recently been debated at the United Nations. The main cause of this shortage is the excessive use of water resources by humans. Therefore, a positive approach to saving water is needed. Much water is used to flush toilets in homes. Thus, it is necessary to develop a sewage disposal system that saves water. We focused on the bowel peristalsis as a model for a mechanism that can transport sludge with little water. In this paper, we suggest a mechanism that uses such a pump and confirmed its capability. In addition, we fabricated a peristaltic pump of six units, and conducted liquid transportation experiments as an operational check.
