1. A method for communicating with a sensing system disposed within a body, the method comprising:

  • placing the sensing system within the body, wherein the sensing system includes an optical module including a plurality of photodiodes that generate a current in response to an incident optical signal used to communicate with the sensing system;

    locating a first interface at a first side of a boundary of the body;

    providing a first optical fiber coupled between the optical module and the first interface such that the first interface is configured to be located at a different location within the body than the sensing system, wherein the first optical fiber, the sensing system and the first interface are located entirely within the body;

    locating a second interface at a second side of the boundary opposite the first interface, the second interface coupled to a second optical fiber; and

    transferring an input optical signal through the second optical fiber and through the boundary of the body into the first optical fiber such that the input optical signal is incident on the plurality of photodiodes,wherein a battery of the sensing system is recharged with the current generated by the plurality of photodiodes in response to the incident optical communication signal and wherein the battery stores electrical energy as chemical energy.
