  • Low power, chemically amplified, electrically removable barrier
    Patent number: 11904045
    Abstract: An implantable device contains a drug or biosensing compound, protected from the external environment within a human body by several barriers which are broken upon activation of the device through electrothermal, chemical, and mechanical processes. The device allows accurate and repeated dosing within a human body, thus reducing the number of implantation procedures required. This device extends the lifetime of a biosensor, reducing the number of implantation procedures required.
    Type: Grant
    Filed: May 14, 2021
    Date of Patent: February 20, 2024
    Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGY
    Inventors: Samson Chen, Axel Scherer, Richard Daniel Smith, Jr.
