Abstract

First and second structures are connected by helical fibers. The orientation between the first and second structures are changed, and by doing so, the positions of the helical fibers are correspondingly changed. The position of change of the helical fibers can be used for a pumping effect, or to change some other fluidic characteristics. One other fluidic characteristics, for example, may use the movement of the helical fibers as a valve.
