Research Progress

  • Abstract
    Battery-less passive computational RFID devices can provide a low cost platform for device manufacturers for secure collection of health telemetry, enabling applications that are currently limited by the battery consumption.

  • Focus of the research/Market need for this project
    Implantable medical devices rely on fixed batteries with finite and limited energy sources. The consumption of resources by active components, including cryptographic engines can be limited by the use of passive RFID technologies such as the Moo. The Moo is a batteryless device, powered by an external RF source and is capable of sensing and collecting data as well as doing cryptographic calculations thereby enabling authentication and key exchange protocols.

  • Project Aims/Goals
    Build a computational RFID platform as a foundation for experiments in secure health data collection.

  • Key Conclusions/Significant Findings/Milestones reached/Deliverables
    The Moo is now on its third revision (Moo 1.2) and is being used in a large variety of projects, both within and outside of the Health IT field. The National Security Agency is now using the Moo to experiment with energy consumption of cryptographic ciphers.

    As of 2013, close to 200 Moo devices have been shipped with orders for more, pending the completion of the next revision of the device.

  • Materials Available for Other Investigators/interested parties
    The Moo is open source, both for the hardware design and software running on the chip. All schematic design documents and source code for the Moo is available at the following URL:

    The Moo also has a support forum for developers and tutorials:

  • Market entry strategies
    We have a directly commercialization path for the development platform. After the completion of the final tests on the Moo1.2, the devices will be available for order at the following URL

    The list of institutions using the Moo device includes: Carnegie Mellon University, Dartmouth College, Duke University, ETH Zurich, The Evergreen State College, Michigan State University, MIT, ORIDAO, Ramtron International Corp., Revere Security, Rice University, Ruhr-University Bochum, ThingMagic, Telecom Lille (Lille University of Science and Technology), Universite de Lille, University of Alabama Birmingham, University of Florida, University of Maryland, University of Massachusetts Dartmouth, University of Michigan, University of Pretoria, University of Washington, U.S. Department of Defense, Weizmann Institute of Science.
