ABSTRACT:
In the present invention, various sizes of non-wetting droplets are inserted into microtube devices of various shapes having therein a gas or wetting fluid which causes the droplets to movement in response to fluid pressure. The droplets may translate within a void of the microtube device which is filled with the gas or wetting fluid or rotate in a fixed position. The nonwetting fluid may also be formed into rings within ring shaped channels. The microtube devices may operate to stop fluid flow, act as a check-valve, act as a flow restrictor, act as a flow regulator, act as a support for a turning axle, and act as a logic device, for example.
