Abstract: This disclosure relates generally to devices, systems, and methods for making a flexible microelectronic assembly. In an example, a polymer is molded over a microelectronic component, the polymer mold assuming a substantially rigid state following the molding. A routing layer is formed with respect to the microelectronic component and the polymer mold, the routing layer including traces electrically coupled to the microelectronic component. An input is applied to the polymer mold, the polymer mold transitioning from the substantially rigid state to a substantially flexible state upon application of the input.

Abstract: Embodiments of the present disclosure describe a wavy interconnect for bendable and stretchable devices and associated techniques and configurations. In one embodiment, an interconnect assembly includes a flexible substrate defining a plane and a wavy interconnect disposed on the flexible substrate and configured to route electrical signals of an integrated circuit (IC) device in a first direction that is coplanar with the plane, the wavy interconnect having a wavy profile from a second direction that is perpendicular to the first direction and coplanar with the plane. Other embodiments may be described and/or claimed.

Abstract: Some forms relate to a stretchable computing device that includes a stretchable body; a first electronic component embedded within the stretchable body; a second electronic component embedded within the stretchable body; and wherein the first electronic component and the second electronic component are connected by stretchable electrical connectors that include vias. The stretchable electrical connectors are non-planar and/or may have a partial zig-zag shape and/or a partial coil shape. In some forms, the stretchable computing device further includes a textile attached to the stretchable body.

Abstract: An optical connector includes a two-dimensional array of lenses to couple optical signals between an optical integrated circuit and an optical fiber. The optical connector has a total-internal-reflection or mirror surface that redirects light between lenses at different surfaces of the optical connector. The lens arrays collimate light directed toward the reflection surface and focuses light received from the reflection surface. The two-dimensional array and prism allows for a low-profile, high-density optical connector based on free space optical light propagation.
