“…Compared to the previous methods, this technique adds an additional feature that allows simultaneous wireless information and power transfer. Due to the nature of RF signal transmissions, the charging distance is longer than in the previous methods, but the overall charging efficiency is much lower, e.g., below 1% [4], especially when the radiation is omnidirectional. In addition, it requires the direct line of sight between the charging and charged devices.…”

In a wireless sensor network (WSN), sensor nodes monitor the physical environment and forward the collected data to a data sink for further processing. Sensors are battery powered and, therefore, prolonging the lifetime of their batteries is critically important. In a rechargeable WSN (RWSN), prolonging the battery lifetime of sensors is achieved through reducing communication energy and recharging the batteries periodically. Reducing the communication energy consumption is done through choosing the best forwarding sensors (i.e., routing) for data collected by each sensor and deciding the transmission power of each sensor (i.e., power allocation). Recharging the batteries is achieved through harvesting energy from external sources. In this thesis, we consider a RWSN that uses wireless power transfer as the energy harvesting technology and jointly optimizes charging and communications in order to minimize the power consumption of the RWSN.

“…Los experimentos revelan que una alta relación de potencia pico a potencia media restringe la potencia máxima de salida de RF para señales multisinusoidales. Incluso con una potencia promedio de entrada similar, las formas de onda de RF de una sola sinusoide producen la mayor eficiencia de receptor y CC-CC [50].…”

“…With advancements in magnetic resonance based wireless energy transfer technology, wireless energy replenishments are now being recently adopted for prolonging lifetime of WSNs. Even though this wireless charging solution is a relatively new technology as at this time, a significant amount of research works have been reported [16]- [21]. This work, therefore, proffers a soft computing technique for easier, rapid and accurate circuital analysis of a wireless mobile charger for research and educational purpose, by training and deploying a tunned Levenberg-Marquardt (LM) trained neural network.…”

Wireless energy transfer is emerging as a promising technology for mobile devices because it enhances rapid charging without requiring conventional cables. In this paper, a wireless mobile charger circuit was designed and simulated, the data obtained thereof was used to train an artificial neural network (ANN) using Levenberg-Marquardt (LM) algorithm. The result obtained was validated against that obtained when trained with regular scaled conjugate algorithm. Analysis of the results showed that the proposed technique remains a viable technique for rapidly analyzing several parts of the wireless mobile charger circuit for design and educational purposes, without always executing computationally intensive and time-consuming simulations.
