INDIVIDUALLY ACTIVATED SENSORS FOR IMPLANTABLE SENSORS

摘要

An apparatus for managing and monitoring a sensing device encapsulated in a compartment formed within a medium is disclosed. The medium compartment includes a release mechanism (210) suitable for exposing the sensing device (310). The apparatus comprises an active component (510) connected to the encapsulated sensing device, the active component providing a measurement from the sensing device to a sensing measurement device. In one aspect of the invention a second active device (420) connected to an electrode associated with the release mechanism, the second active component (420) selectively providing an electrical signal to the electrode for activating the release mechanism (210) and exposing the encapsulated sensing device (310). In another aspect of the invention, a plurality of the apparatus disclosed may be incorporated into an array that is electrically connected to a select circuit for providing a voltage to selected ones of the first and second active devices for switching the active devices to a conductive state. A release circuit selectively provides a voltage to selected ones of the second active device (420), wherein the voltage is suitable for operating an associated compartment release mechanism and exposing the associated sensing device.
