Abstract
A device configured to fit between an electric plug and an electric wall outlet for monitoring the energy consumption of an electrically powered device such as an appliance. The monitoring device enables energy consumption to be measured over time and reported to an RFID reader without the need to interrupt the power supply to the device being monitored. The monitoring device comprises a detection circuit coupled to a transmission system attached to a thin, planar base. A field powering element within the detection circuit is used to achieve electric field powering of the monitoring device.
