Abstract: A method of processing a glass substrate including texturing the glass substrate to form a textured surface that includes a plurality of micro fractures extending from the textured surface into the substrate. And, thereafter, chemically etching the textured surface of the glass substrate to a depth sufficient to remove the micro fractures. The glass substrate can then be chemically strengthened after the etching step.

Abstract: Disclosed herein is a substrate for an electronic device. The substrate has a visually imperceptible surface texture that exhibits different coefficients of friction on various input objects. In some implementations, the texture of the textured substrate is created using a gas etching process.

Abstract: The disclosure relates to an audio device that includes a diaphragm having a graphene material, such as a graphene flake, that is incorporated into a base material. The audio device may form part of a speaker device, a microphone device, or a headphone device. The concentration of the graphene and/or a size of the graphene flakes may be varied throughout the diaphragm to define a stiff center portion and a flexible portion that surrounds the center portion.
