  • Switchable objects and methods of manufacture
    Patent number: 11537021
    Abstract: A simplified switchable object and methods of making same are provided. The methods may include steps of applying a switchable material on a first surface of a first substrate, the switchable material having a thickness and a shape; applying a barrier material on the first substrate, circumferential to the switchable material; and applying a second substrate over top of, and in contact with, the switchable material and the barrier material, the first substrate, second substrate and barrier material defining a closed chamber encapsulating the switchable material. The methods may further include a step of applying a seal material.
