In this article, we use a conversion chain to minimize standby-mode power consumption, detailing the different parts of the emitter and the receiver. The proposed technology is based on an efficient radio-frequency (RF) energy transfer and an RF-dc conversion circuit with a self-maintained switch that wakes up an electronic device [e.g., television (TV), home automation systems, etc.], using an integrated emitter and a receiver with performances suitable for home or industrial applications. The developed system works in the industrial, scientific, and medical (ISM) band (2.4-2.48 GHz).
