Structurally embedded and inhospitable environment systems and devices having autonomous electrical power sources

An embeddable integrated electrical package, comprising:

• at least one electrically-driven component;
• an electrical power source component configured to provide an electrical energy source for the at least one electrically-driven component, the electrical power source component comprising:
• a first conductor, formed of a first conductive material and having a first surface and a second surface, the first surface of the first conductor facing away from a build surface and being conditioned to have a work function in a range of 1.0 electron volts (eV) or less,
• a dielectric layer with a thickness of 200 angstroms or less formed over the conditioned first surface of the first conductor, and
• a second conductor, formed of a second conductive material and having a first surface with a work function in a range of 2.0 eV or greater, and a second surface, arranged over the formed dielectric layer such that the first surface of the second conductor faces the dielectric layer,
• the first conductor, the dielectric layer and the second conductor forming a layered structure of an electrical power source component element;
• a first electrical lead and a second electrical lead electrically connecting the at least one electrically-driven component and the electrical power source component;
• and
• an encasement for the at least one electrically-driven component and the electrical power source component forming a common outer shell to provide the embeddable integrated electrical package.
