Abstract :
The use of chaotic signals as an optimal source for wireless power transmission as well as electromagnetic energy harvesting is proposed. The improved performance of rectifier circuits, in terms of higher RF to DC conversion efficiency, when using chaotic signals in comparison to one-tone signals is demonstrated. A 433MHz chaotic generator and a rectifier circuit are designed and implemented in order to demonstrate the improved efficiency of the system when using chaotic waveforms.
