1. A device for the controlled delivery or exposure of reservoir contents comprising:

  • a substrate having at least one reservoir, each reservoir having at least one opening;

    reservoir contents disposed in the at least one reservoir;

    a reservoir cap formed of an electrically conductive material and closing off the opening, to seal the reservoir contents in the at least one reservoir; and

    control circuitry and a power source for selectively disintegrating the reservoir cap, thereby opening the reservoir to release or expose the reservoir contents,wherein the reservoir cap comprises multiple metal layers or multiple layers of metal and semiconductor,wherein the control circuitry comprises an electrical input lead and an electrical output lead, which leads are electrically and mechanically connected to the reservoir cap.
