A compact, hand-held device for wireless powering, interrogation and data
retrieval from at least one implanted sensor. The hand-held device
includes an antenna for powering an implanted sensor and for receiving
data from the implanted sensor to the hand-held device for at least one
of storage, display or analysis. The hand-held device establishes
electromagnetic coupling with a low radiating radio frequency power
inductor in the implanted sensor at a predefined separation and the
antenna geometry allows for the antenna to power, interrogate and
retrieve data from the implanted sensor without strapping the hand-held
device to a human body housing the implanted sensor The hand-held device
optionally allows for activation of the implanted sensor only during
interrogation and data retrieval.
