Abstract

The ultimate challenge for next generation XR devices, like smart glasses, is the integration of optics and electronics in a lightweight and unobtrusive device. On this path, miniaturization is an essential key factor, in which adhesives and functional polymers play a vital role. The latest generation of adhesives and functional polymers are not only used for conventional bonding tasks but can exhibit special properties to fulfill additional jobs such as active alignment of projector devices or in- and outcoupling of light into the optical waveguide by imprinting a polymer grating structure directly on the glass substrate. Next to the additional functionality, the clear advantage of a polymer is the combination of a comparably low mass to minimize weight, dispensing in arbitrary shapes for maximum flexibility and miniaturization and finally easy and fast processing, which results in high yield and units per hour in a mass production process.
