A systematic approach for performing literature reviews in electrical engineering

Bibliographic reviews can be limited when researchers face more specific and new challenges. One rising way to solve this is the systematic review. When performing one, there is a well-defined search, treatment, analysis, and display methodology, which follows the scientific method. In this paper, we propose a systematic review methodology for the electrical engineering field. This kind of methodology allows more objective, concrete, and useful results; bias reduction; and easy reproducibility. For clarification purposes, we provide a case study on sensors, transducers, and actuators for controlled environment agriculture, in which the methodology is applied.
