Abstract
A fluid-tight envelope () encloses an RFID chip (), a first array of conductors (-) on an internal surface (), and a second array of conductors (-) fixed to an opposing internal surface () of a flexible outer wall () of the envelope (). The outer wall () is urged inwardly by ambient pressure to press the conductors of the second array (-) into electrical contact with the conductors of first array (-) to thereby form an antenna (). Fluid pressure in the chamber () that holds the antenna () tends to displace the outer wall () outwardly to thereby separate conductors of the first and second arrays (--).
