  • Publication number: 20230287232
    Abstract: This invention discloses formulations of mutually compatible sets of graphene, graphene-carbon, metal and dielectric inks for the fabrication of high performance membrane touch switches (MTS). The compositions of these inks are optimized to achieve higher degree of compatibility with highly engineered polymeric substrates, thereby offering a holistic solution for fabricating high-performance MTS. These sets of materials can also be used for fabrication of sensors, biosensors and RFIDs on flexible substrates, such as polymers and papers.

  • Patent number: 11275793
    Abstract: The disclosure describes techniques for generating device recommendations. The techniques include registering a plurality of Internet of Things (IoT) devices in a social IoT network, where each device performs one or more tasks and the one or more tasks include a first task. The techniques include periodically receiving, with the social IoT network, a work profile from one or more of the registered devices. The work profile includes device information associated with the one or more device tasks performed by the respective registered device. The techniques include grouping devices performing the first task into groups of similar devices, identifying, based on the device information in the work profile received from one or more of the registered devices, at least one device from the group of devices for which recommendations are to be provided, generating the recommendations for the identified device, and providing the recommendations for the identified device.

  • Publication number: 20180072573
    Abstract: A method of synthesizing high quality graphene for producing graphene particles and flakes is presented. The engineered qualities of the graphene include size, aspect ratio, edge definition, surface functionalization and controlling the number of layers. Fewer defects are found in the end graphene product in comparison to previous methods. The inventive method of producing graphene is less aggressive, lower cost and more environmentally friendly than previous methods. This method is applicable to both laboratory scale and high volume manufacturing for producing high quality graphene flakes.
