    摘要: A method is provided that integrated a unique set of structural features for concealing self-powered sensor and communication devices in aesthetically neutral, or camouflaged, packages that include energy harvesting systems that provide autonomous electrical power to sensors, data processing and wireless communication components in the portable, self-contained packages. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below. The layers uniquely implement optical light scattering techniques to make the layers appear opaque when observed from a light incident side, while allowing at least 50% and as much as 80+%, of the energy impinging on the energy or incident side to pass through the layer.

    摘要: A method for forming a unique, environmentally-friendly energy harvesting element is provided. A configuration of the energy harvesting element causes the energy harvesting element to autonomously generate renewable energy for use in electronic systems, electronic devices and electronic system components. The energy harvesting element includes a first conductor layer, a low work function layer, a dielectric layer, and a second conductor layer that are particularly configured in a manner to promote electron migration from the low work function layer, through the dielectric layer, to the facing surface of the second conductor layer in a manner that develops an electric potential between the first conductor layer and the second conductor layer. An energy harvesting component is also provided that includes a plurality of energy harvesting elements electrically connected to one another to increase a power output of the electric harvesting component.

    摘要: An electrically-powered device, structure and/or component is provided that includes an attached autonomous electrical power source in a form of a unique, environmentally-friendly structure that is configured to transform thermal energy at any temperature above absolute zero to an electric potential without any external stimulus including physical movement or deformation energy. The autonomous electrical power source component provides a mechanism for generating renewable energy, or a renewable energy supplement, as primary or auxiliary power for the electrically-powered device, structure and/or component. The autonomous electrical power source component is formed of one or more elements, each of which includes a first conductor having a surface with a comparatively low work function, a second conductor having a surface with the comparatively high work function and a dielectric layer on a scale of 200 nm or less interposed between the conductors.
