  • Patent number: 10254620
    Abstract: The invention includes photoelectrophoretic displays and methods for creating reflective images using photoelectrophoretic displays. A photoelectrophoretic display typically includes a transparent electrode, an encapsulated photoelectrophoretic medium, and a rear electrode. An image is created by supplying an electrical potential between the electrodes that is insufficient to cause the photoelectrophoretic particles to move to the transparent electrode in the absence of incident light. In the presence of incident light, however, the photoelectrophoretic particles move to the viewing surface (transparent electrode), thereby producing an image.

  • Patent number: 8758650
    Abstract: Graphene-based thermopiles are provided. The graphene-based thermopiles may include thermocouples having one or more graphene strips that may be polarized to adjust their Seebeck coefficients. The polarized graphene strips may have larger Seebeck coefficients than the materials conventionally used in thermopile devices. As a result, the graphene-based thermopiles may generate large output voltages using fewer thermocouples than conventional thermopile devices.
