  • Patent number: 9797779
    Abstract: Graphene and ferroelectric materials are used as tunable sensors for detecting and measuring radiation, such as infrared radiation. The low absorption and reflectance of graphene and interconnected graphene networks, for example in the infrared, are exploited for use in such tunable sensors. The active layer makes use of a unique property of ferroelectric materials, known as the pyroelectric effect, for measuring the intensity of impinging radiation. Using graphene electrodes may offer a significant increase in sensitivity, tunability and mechanical flexibility of sensors, such as infrared sensors. In one method, intensity of radiation is measured using variations in the doping level of the graphene electrode.

  • Publication number: 20160259224
    Abstract: In accordance with a version of the invention, graphene with a ferroelectric material is used as the transparent electrode material in an electrochromic device. The use of curved and dynamically flexing substrates enables flexible and stretchable applications for electrochromic films. Furthermore, the nonreactive and impermeable nature of graphene increases the durability of the device through increased resistance to external impurities. In addition, the incorporation of ferroelectric materials allows the device to exhibit nonvolatile usage; that is, devices can remain transparent with no external power source. Furthermore, devices may exhibit a charging effect, permitting recovery of energy stored in alignment of ferroelectric dipoles within the ferroelectric material.
