Devices are provided for the controlled exposure or release of contents stored in hermetically sealed reservoirs. The devices comprise a primary substrate having a front side and a back side, and including one or more hermetic sealing materials; a plurality of reservoirs in the primary substrate positioned between the front side and the back side; reservoir contents, which comprise chemical molecules (such as drugs) or a secondary device (such as a glucose sensor), located inside the reservoirs; a hermetic sealing substrate having a surface composed of one or more hermetic sealing materials; and a hermetic seal formed between and joining the primary substrate and the hermetic sealing substrate, wherein the hermetic seal independently seals the reservoirs.
