  • Implantable Dissolved Oxygen Sensor and Methods of Use
    Publication number: 20210030321
    Abstract: A sensor is provided for measuring a dissolved oxygen concentration in vivo when implanted at a tissue site and in ex vivo applications. The sensor includes an article comprising a sensing medium retained within the implantable article by an oxygen-permeable material. The sensing medium comprises an MR contrast agent for oxygen. The sensor is configured to indicate the dissolved oxygen concentration of a fluid, e.g., in vivo at the tissue site, when subjected to an MR-based method.

  • Biometric Device and Means for Electronic Storage and Retrieval of Biometric Data
    Publication number: 20170205406
    Abstract: A biometric device, comprising a solid support suitable for receiving biological material and for dry storing that material at room temperature the device further comprising a circuit including means for two way radio frequency communication and including writable data storage. A processing method for such biometric devices, the method including the steps of: a) identifying said device by means of RF communication; b) extracting at least a portion of the biological material from the solid support of the identified device; c) analysing the extracted biological material to obtain biometric data indicative of the biological material; and d) writing said biometric data to the data storage of the biometric device.
