  • Patent number: 11931159
    Abstract: A textile-based hydrogel electrode comprises a textile-based backing layer, a conductive structure coupled to the textile-based backing layer, and a hydrogel body in contact with at least a first portion of the conductive structure, wherein the first portion of the conductive structure and the hydrogel body form an ionic interface configured to generate an electrical signal through the conductive structure corresponding to a biopotential change proximate to the textile-based hydrogel electrode.
    Type: Grant
    Filed: November 6, 2020
    Date of Patent: March 19, 2024
    Assignee: University of Massachusetts
    Inventors: Seyedeh Zohreh Homayounfar, Ali Kiaghadi, Soha Rostaminia, Deepak Ganesan, Trisha L. Andrew
  • Publication number: 20230381677
    Abstract: A plush toy system comprises a plush toy body with an outer fabric layer, wherein the outer fabric layer forms an interactive surface engageable by a user, an array of textile-based pressure sensors coupled to the plush toy body proximate to the outer fabric layer, and sensor conditioning circuits coupled to the plush toy, the sensor conditioning circuits being configured to interpret signals from the textile-based pressure sensors to identify interaction between the user and the interactive surface.

  • Publication number: 20220386957
    Abstract: A garment system comprises a garment substrate formed from one or more textile-based sheets, a distributed array of a plurality of resistive pressure sensors coupled to the garment substrate at a set of first specified locations. Each of the plurality of resistive sensors comprises a pair of first textile-based outer layers each having an electrical resistance of no more than 100 ohms and a textile-based inner layer sandwiched between the pair of first textile-based outer layers having an electrical resistance of at least 1 mega-ohm. The system also includes electronics configured to process signals from the distributed array of resistive pressure sensors to determine one or more physiological properties of a wearer of the garment substrate.

  • Patent number: 10572701
    Abstract: Systems and techniques for a low power wrist-worn RFID reader capable of reading RFID tags within the area of a localized personal body network. The wrist-worn reader provides a means for tracking how a user interacts with their environment. The wrist-worn reader may distinguish between tagged objects within the range of the reader and objects held by the user. The reader may also distinguish when a tagged object has been picked up and when it has been released.
