An apparatus for power generation. The apparatus has a first substrate comprising a conductive surface region and a second substrate coupled to the first substrate. Preferably, the second substrate comprises an electret material region, which is characterized by a substantially uniform electric field associated with the electret material region. The conductive substrate and the electret substrate are aligned in a significantly parallel fashion with a common area of each region directly facing the other region (A). A distance (d) characterizing a spatial separation is formed between the conductive surface region and the electret material region. A relative voltage potential (V) between the conductive substrate and the electret substrate is associated with the distance (d). In between the conductive substrate and the electret substrate is a material, liquid, gas, or combination with an associated permittivity (epsilon0). The relative voltage potential changes based upon a change in the spatial separation between (d), a change in the overlapping area (A), or a change in the permittivity (epsilon0) between the conductive surface region and the electret material region.
