An omnidirectional structural color pigment having a protective coating. The pigment has a first layer of a first material and a second layer of a second material, the second layer extending across the first layer. In addition, the pigment reflects a band of electromagnetic radiation having a predetermined full width at half maximum (FWHM) of less than 300 nm and a predetermined color shift of less than 30&#xb0; when the pigment is exposed to broadband electromagnetic radiation and viewed from angles between 0 and 45&#xb0;. The pigment has a weather resistant coating that covers an outer surface thereof and reduces a relative photocatalytic activity of the pigment by at least 50%.

Non-color shifting multilayer structures and protective coatings thereon

A triboelectric generator includes a resiliently-deformable hexagonal housing including a first housing wall and a second housing wall positioned opposite the first housing wall. A first electrode resides along the first housing wall, and a second electrode resides along the second housing wall. A dielectric contact layer is positioned in intimate contact with the first electrode and between the first electrode and the second electrode. The dielectric contact layer is spaced apart from the second housing wall. The first housing wall is coupled to the second housing wall such that at least one of the first housing wall and the second housing wall is resiliently movable toward the other one of the first housing wall and the second housing wall so as to enable contact between the dielectric contact layer and the second electrode during operation of the triboelectric generator.

Triboelectric generator and network for mechanical energy harvesting

An elastomeric triboelectric generator housing structured for incorporation into a wheel for a vehicle is provided. The housing includes a least one cavity having a pair of opposed walls, and a triboelectric generator incorporated into the at least one cavity. The at least one cavity is structured to actuate responsive to application of at least one force to the housing along an axis extending through the at least one cavity and between a central axis of the housing and a circumference of the housing.

Triboelectric generator housing and system for vehicle wheel

A system includes a shell at least partially formed in a shape of a steering wheel and having a first layer and a second layer spaced apart from one another. The system further includes an LED coupled to the shell or the steering wheel. The system also includes a positive triboelectric material coupled to the first layer of the shell and that loses electrons in response to friction. The system further includes a negative triboelectric material coupled to the second layer of the shell and that gains electrons in response to friction. The system further includes an electrical connector coupled to the LED and at least one of the positive triboelectric material or the negative triboelectric material. Current flows through the electrical connector to illuminate the LED when force is being applied to the shell causing the positive triboelectric material to contact the negative triboelectric material.

A process of forming a multi-layered pigment includes the steps of: providing a metal core material; dispersing the metal core material in a first solvent and organic binder mixture; depositing a high refractive index material onto the metal core material; drying the deposited high refractive index and metal core material wherein the high refractive index layer is uniform and crack-free.

PEG-assisted deposition of crack-free titania nanocrystalline coatings over Al flakes

A process of forming a multi-layered pigment comprising the steps of: providing a metal core material; treating the metal core material with an acid, depositing a passivation layer onto the metal core material; densifying the metal core material having the passivation layer reducing a pore size of the passivation layer; and depositing a high refractive index material onto the sintered material wherein the high refractive index layer is uniform and crack free.
