Wireless power transmission was conceptualized nearly a century ago. Certain achievements made to date have made power harvesting a reality, capable of providing alternative sources of energy. This review provides a summ ary of radio frequency (RF) power harvesting technologies in order to serve as a guide for the design of RF energy harvesting units. Since energy harvesting circuits are designed to operate with relatively small voltages and currents, they rely on state-of-the-art electrical technology for obtaining high efficiency. Thus, comprehensive analysis and discussions of various designs and their tradeoffs are included. Finally, recent applications of RF power harvesting are outlined.

“…For example, in the PWM control, the output voltage will be compared with a reference voltage through an error amplifier, and then a triangular wave will be modulated with the output of the amplifier to get the rectangular pulses with a certain duty cycle. There was also the control method by using the input voltage of the DC-DC circuit as a reference voltage to modulate a triangular wave whose amplitude proportional to the output voltage [47].…”

Abstract:The abundant mechanical vibration energy in bridge road environment can be converted into electric energy by using the piezoelectric energy harvest technology, which could be an efficient way to provide energy required by the wireless sensor network in the bridge condition monitoring system. An autonomous energy harvesting system has been designed based on cantilever beams for sensing and acquiring the bridge vibration energy. After the analysis of the dynamic properties of the piezoelectric cantilever beam in the energy conversion, three kinds of interface circuits were compared through simulation and experimental results. It was shown that the VD interface circuit has less power loss. Furthermore, the proposed closed loop control method based on the VD circuit was simple, adaptive, and self-powered, which is suitable for the road energy harvesting application. Finally, the energy harvesting system based on VD circuit was realized with harvested power of around 0.8mW.Keywords: piezoelectric cantilever energy harvester 1; autonomous 2; adaptive 3; self-powered 4; voltage doubler interface circuit 5; closed loop control 6; feed-forward 7; multi-shot technology 8

“…Harvester configuration has been studied with the basic concept remain ing the same. The core principle is that the vibrations of magnetic field is lin ked as per Faraday's law to induce a current which can then drive an electrical device [2]. Ferrofluids have attracting application in various fields like automobiles, electrical engineering [28,30,31,32], space technology, computer science, med ical imaging, bio med ical [3,4], targeted drug delivery [5,6], optical fiber [27,29] and sensors [7,8] etc.…”
