Multi-material eyewear device

Abstract

A multi-material eyewear device that can be utilized in an augmented reality (AR) or mixed reality (MR) eyewear display system includes an upper portion composed of a different material from one or more lower portions. The upper portion has a higher stiffness or stiffness-to-mass ratio than the lower portions, is less RF-permeable than the lower portions, and/or has a higher thermal conductivity than the lower portions. One or more antennas bonded to, housed in, or coextensive with the lower portions operate with high performance and efficiency due to the lower portions having higher RF-permeability than the upper portions, while the multi-material eyewear device maintains a high overall stiffness or stiffness-to-mass ratio due to the stronger material of the upper portion.
