Abstract
A multilayered impedance pump is formed by an inner tube and an outer tube which have different mechanical characteristics. The outer tube is relatively stiff, and can be used for a structural material. The inner tube is excitable, and a gel is placed between the inner and outer tube. The actuator actuates the gel to cause pressure waves along the inner tube.
