摘要: A system is provided that integrates an autonomous energy harvesting capacity in a mobile device in an aesthetically neutral manner. A unique set of structural features combine to implement a hidden energy harvesting system on a surface of the mobile device body structure or casing to provide electrical power to the mobile device, and/or to individually electrically-powered components in the mobile device. 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 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 system and method are provided for forming energy filter layers or shutter components, including energy scattering layers that are actively electrically switchable. The energy filters or shutter components are operable between at least a first mode in which the layers, and thus the presentation of the shutter components, appear substantially transparent when viewed from an energy/light incident side, and a second mode in which the layers, and thus the presentation of the energy filters or shutter components, appear opaque to the incident energy impinging on the energy incident side. The differing modes are selectable by electrically energizing, differentially energizing and/or de-energizing electric fields in a vicinity of the energy scattering layers. Refractive indices of transparent particles, and the transparent matrices in which the particles are fixed, are tunable according to the applied electric fields. The energy scattering layers may conceal a sensor such as a camera or photovoltaic cell.
