Abstract: Methods and apparatuses for capturing at least a portion of the radio frequency (“RF”) radiation emitted from an electronic device or other external sources and converting it into electric current that can be used for a number of different functional purposes including to drive a circuit that provides an indication when the RF radiation is captured and its relative intensity. One of the advantages of these techniques is that users can be protected from the potential harmful effects of long-term exposure to the RF radiation emitted from electronic devices, particularly for wireless phones which are often held in close proximity to a user's body. The indication can provide users with an indication that the circuit is redirecting the RF radiation away from their bodies and dissipating it as electrical energy.
