1. An energy conversion device using built-in potential difference of metal-to-metal junctions, in which a charge shuttle device is used the energy conversion device comprising:

  • a capsulation, which is fixed within a reference frame of the device, but is subject to external motion and encapsulates all the device components;

    a plurality of device first electrode and a device second electrode wherein the device first electrode is mechanically coupled to the capsulation, wherein the device second electrode is mechanically coupled to the capsulation;

    a moving shuttle that moves back and forth between the device first electrode and the device second electrode wherein external motion is exerted to the moving shuttle, and the moving shuttle cannot be in electrical contact with the device first electrode and the device second electrode at the same time;

    a device first electrode node connected to the device first electrode;

    a device second electrode node connected to the device second electrode; and

    a device shuttle node connected to the device shuttle electrode;

    wherein an electrical energy is generated through the relative motion of the shuttle with respect to the device first electrode and the device second electrode, as a result of contact or proximity based charging due to contact potential differences of the materials making up the shuttle and the device first electrode and the device second electrode.
