Patent number: 10818433Abstract: Dielectric ceramic particulates are introduced into thin a sheet of pre-cured elastomer to form a sheet. Successive layers of the sheets may then be laminated together to form a finished article. An electric field may be applied to the article during a curing process while the article is at a temperature near a Curie temperature of the dielectric ceramic particulates to increase a dielectric constant of the article. As each sheet may be different from each other in the finished article, the resulting finished article may have anisotropic dielectric and mechanical properties. Similarly, tiled dielectric ceramic structures may be introduced into the elastomers layers to generate materials with varying dielectric constants.Type: GrantFiled: September 20, 2019Date of Patent: October 27, 2020Assignee: Facebook Technologies, LLCInventors: Sean Jason Keller, Tristan Thomas Trutna, Vincenzo Casasanta, III, David R.
