per·i·stal·sis

(pĕr′ĭ-stôl′sĭs)
The wave-like muscle contractions in the organs of the digestive tract that push food into the stomach and then to the intestines. Peristalsis starts in the esophagus and ends when digested food is eliminated as waste.

peristalsis

the process of contraction and relaxation by which products are moved through the alimentary canal. Cf. diastalsis.peristaltic, adj.

Instead, it gets its power from the churning motion of the stomach during peristalsis. Because the movement of the stomach provides the device with its power, it only works when the arrival of food causes the stomach to move; this means that the device is only active at the precise time its signals will be effective.
