  • Publication number: 20230358625
    Abstract: Gravity-actuated display systems suitable for use as security markers, for example to incorporate into bank notes. The devices can be made very thin and flexible, yet are robust enough to endure the harsh conditions of paper currency in general circulation. Because the displays are gravity actuated, they do not require a power source or circuitry. The gravity-actuated displays can be fabricated using microembossing or photolithography and can be filled and sealed using roll-to-roll techniques. The microcells can also be patterned to provide custom designs, such as official seals.

  • Publication number: 20230324761
    Abstract: The present invention is directed to a sealing layer that comprises a combination of polyurethane and poly(vinyl alcohol), the poly(vinyl alcohol) containing an acetoacetate functional group in its molecular structure. The sealing layer is formed from an aqueous sealing composition and shows water resistance and good barrier properties to non-polar fluids. The sealing layer can be used to seal microcells of electro-optic displays.

  • Publication number: 20230276710
    Abstract: Piezoelectric films including ionic liquids and methods of making piezoelectric films including ionic liquids. The resulting films have higher levels of beta phase and can be poled using external fields without additional treatment, such as stretching. The films are light-transparent. In some embodiments, the piezoelectric material is used to create piezo-electrophoretic films that can be patterned for use as security markers, authentication films, or sensors. The films are generally flexible. Some films are less than 100 ?m in thickness. Electrophoretic displays formed from the piezoelectric films do not require an external power source.
