Abstract: A method of operating a liquid lens can include positioning a variable interface between first and second liquids in a brace position in response to a brace trigger event. The variable interface can be adjustable between (a) a rest position in which a perimeter of the variable interface is spaced from a first window of the liquid lens by a rest distance and (b) the brace position in which the perimeter of the variable interface is spaced from the first window by a brace distance. The brace distance can be greater than the rest distance. In the rest position, the variable interface can have a rest surface area. In the brace position, the variable interface can have a brace surface area. The brace surface area can be less than the rest surface area.

Abstract: Foldable substrates comprise a first portion, a second portion, and a central portion positioned therebetween. The central portion comprises a first transition region comprising a first transition width and a first transition surface area extending between a first surface area of the first portion and a first central surface area of the central portion with a first average angle. In aspects, the first average angle is from about 167° to about 179°. In aspects, the first transition width is from about 150 micrometers to about 700 micrometers. Methods comprise disposing an etch mask over the first major surface of the foldable substrate before etching the foldable substrate. In aspects, the etch mask comprises a first polymer layer positioned between a first barrier layer and the first major surface. In aspects, the etch mask comprises a positive photoresist.

Abstract: A liquid lens can include a first substrate with an interior recess. A second substrate with a bore can be bonded to the first substrate, whereby the interior recess of the first substrate and the bore of the second substrate cooperatively define at least a portion of a cavity of the liquid lens. A first liquid and a second liquid can be disposed in the cavity. A variable interface can be disposed between the first liquid and the second liquid, thereby forming a variable lens. The interior recess of the first substrate can be positioned outside of a sidewall projection of a sidewall surface of the cavity through the first substrate.
