Abstract
INTRODUCTION. In recent years, alternative energy sources have become essential as their demand increases, energy obtained from external sources such as thermal, solar, wind and Radio Frequency (RF), have been used for various purposes to provide unlimited and sustainable energy for the lifetime of electronic devices. OBJECTIVE. This research focuses on the concept of Energy Harvesting and the review of different energy harvesting systems in order to identify their relevant data, as well as the electrical characteristics of each of the systems and elements that are indispensable for their construction. METHOD. In this documentary review of energy harvesting systems, qualitative research is proposed with the review of articles and scientific studies dedicated to the research of energy harvesting. RESULTS. Different parameters have been identified such as: frequency, operating bands, gain, antenna type, type of signal collected, power, load resistance, and storage. DISCUSSION AND CONCLUSION. The rectifier configuration that has had the highest conversion efficiency was the voltage double, followed by the series diode rectifier.
