1. A fluid aggregator for aggregating fluid flow into an inlet of a piezoelectric pump, the fluid aggregator comprising:
a member having a first side, a second side opposite the first side, a first end between the first side and the second side, a second end opposite the first end, and a third end perpendicular to and extending from the first end to the second end;
a cavity disposed in the second side and having an area less than an area of the second side;
a channel disposed in the cavity, the channel having an area less than the area of the cavity;
a fluid lumen through the member from the channel to the first side;
the channel comprising a first arm and a second arm, a union of each arm with adjacent arms of the second side being positioned at the fluid lumen;
a conduit coupled to the first side, the conduit having at least one lumen fluidly coupled to the fluid lumen;
a first notch extending into the third end of the member, the first notch having a length extending into the cavity and a depth substantially equal to a depth of the member; and
a second notch extending into the third end of the member, the second notch having a length extending into the cavity and a depth substantially equal to a depth of the member.
