1. A manufacturing process comprising:

  • loading a first portion of a tablet material into a press, the tablet material formulated to disintegrate upon contact with a fluid;

    loading an ingestible event marker into the press adjacent to the first portion of the tablet material, the ingestible event marker comprising;

    a partial power source having a first portion and a second portion and configured to generate power upon contact of the first portion and the second portion with the fluid; and

    a control unit electrically coupled between the first portion and the second portion of the partial power source, wherein the control unit is configured to be activated by receiving the power from the partial power source and to encode information in a current flow between the first portion and the second portion through the fluid;

    loading a second portion of the tablet material into the press on a side positioned opposite of the ingestible event marker from the first portion of the tablet material, such that the ingestible event marker resides in the press between the first portion and the second portion of the tablet material;

    applying pressure in the press to the first and the second portions of the tablet material, such that the first portion and the second portion of the tablet material completely encapsulates the ingestible event marker and the first portion and the second portion of the partial power source are exposed after the first portion and the second portion of the tablet material disintegrates upon contact with the fluid; and

    covering at least partially the first portion and the second portion of the tablet material with a non-soluble film material to form an ingestible device, wherein the film material is formulated and configured to inhibit interaction between the tablet material and a pharmaceutical product during disintegration of the pharmaceutical product; and

    wherein the film material covers at least partially the first portion and the second portion of the tablet material such that when the first portion and the second portion of the tablet material come in contact with the fluid, the film material controls the direction of expansion of the tablet material as the tablet material expands.
