Abstract:
Components of an electronic device, such as glass components, are susceptible to surface damage. Glass components can be strengthened by providing ceramic particles at the exposed surface of the glass. Ceramic particles can also provide optical features, such as color, opacity, and haze to enhance the appearance of the resulting composite article. Where ceramic particles are provided at the exposed surface, the ceramic particles can also produce a desired tactile feature. These features can be provided in various combinations and in different ways across different regions to produce a desired look and feel of the resulting composite article.
Abstract:
Flexible photonic crystal structures capable of changing color in response to strain are described. Methods for forming two-dimensional and three-dimensional flexible photonic crystal structures are described. In some aspects, the flexible photonic crystal structures include an array of holes or voids formed within a flexible material. The flexible material changes dimensions of the array when the flexible photonic crystal structures is stretched, pulled, pushed or bent. In some aspects, the flexible photonic crystal structures include an array of features made of a first material, such as a first type of polymer, embedded within a matrix material made of a second material, such as a second type of polymer. The flexible photonic crystal structures can be used in the manufacture of consumer products, such as electronic products, electronic product accessories, thin films, flexible displays and wearable products.
