  • Publication number: 20220018247
    Abstract: A method and apparatus for establishing a secure communication link between a first member and a second member in a wellbore. The apparatus includes a strain sensor and at least one processor. The strain sensor is at a mating end of the second member and measures a strain at the mating end.
