In this review, we mainly focus the novel understanding categories of transducer. Today's manufacturing sector uses analytical and managerial techniques in increasing quantities to increase productivity and minimise costs on all areas; economic, ecological, and energyrelated. Additionally, industries frequently require energy conversion from a particular type to a different one. Especially, when it comes to long distance and mass communication, we need conversion of sound energy to electrical energy. Transducer is very helpful in this process. The aim of this paper is to perform a basic but systematic review of the electropassive transducer based on transduction and the classification including the working mechanism. The systems reviewed based on their operational principle, primary introduction, classification based on numerous activities, the identical parameters, and specific features, provides the various taxonomy about the subdivision of the transducer based on their operational and transduction phenomena including their sensing mechanism. Through signal input is required for changes of physical to electrical transducer based on transduction, e.g., resistive, capacitive, inductive. This review focuses on an electro-passive phase having different mechanism based on the transduction principle. Technologies that have been in use for a while as well as those that are still in the early stages of development are all featured together. Lastly, the readily available. An outlook for prospective future developments is presented, along with a summary of the instruments
