SALAZAR, Fabian; NUNEZ, Maritza; CUJI, Julio  y  GORDON, Carlos. Architectures of Energy Harvesting Systems. Enfoque UTE [online]. 2021, vol.12, n.4, pp.45-57. ISSN 1390-6542.

This article develops the literary review of the architectures of energy harvesting systems, identifying parameters such as: frequency, type of antenna, architecture (elements), among others. The methodology has four stages: a) Search for documentation, 10 systems were obtained, which were designated with the letter "S" accompanied by the article number; b) Reading of scientific documents; c) Extraction of information and architecture of the systems, where the stages of each system are detailed (which vary from 2 to 4), the working frequencies (300 KHz to 3.43 GHz, 2.45 GHz being the most used in systems for collecting radio frequency energy). In addition to using in certain systems, multiplier and rectifier circuits in different configurations: half wave, full wave; to later be stored in batteries or directly applied to devices; d) Documentation of the information extracted. Finally, after completing the literary review, it was observed that, in most articles, the systems have 3 stages: antenna, coupling, and rectification that transforms the received energy (alternating current) into direct current, their operation varies in frequency intervals of 1.8 to 2.4 GHz depending on the configuration of each system. Likewise, the product obtained is a consultation APP, with a selection menu of the different architectures investigated, which is a very beneficial contribution for researchers who wish to work in this area.
