1. An apparatus for manipulating droplets, the apparatus comprising:

  • (a) a first printed circuit board substrate comprising a first side surface and a second side surface;

    (b) an array of drive electrodes disposed on the first printed circuit board substrate first side surface;

    (c) a dielectric layer disposed on the first printed circuit board substrate first side covering the drive electrodes;

    (d) a second substrate comprising a first side surface and a second side surface, the second substrate being substantially parallel to and spaced apart from the first printed circuit board substrate by a distance to define a space between the second substrate second side surface and the first printed circuit board substrate first side surface, wherein the distance is sufficient to contain a droplet disposed in the space; and

    (e) one or more reference elements disposed on the second substrate second side surface.
