Abstract: An electret device. The device has a thickness of substrate material having a contact region. An electrically floating conducting region is formed overlying the thickness of substrate material. The floating conducting region is free from physical contact with the contact region. A protective layer is formed overlying the floating conductive layer. The protective layer has a surface region and seals the floating conducting region. The thickness of substrate material, floating conducting region, and protective layer form a sandwiched structure having a charge density of at least 1 X 10-4 Coulombs/m2 and a peak to peak charge uniformity of 5 % and less.

Abstract: 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 (e0). 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 (e0) between the conductive surface region and the electret material region.
