Abstract :
The present paper provides a basic ultrasonic system based in a C-mode using a piezoelectric ceramic as a transmitter and a PVDF polymer as receiver and its behavior in several acoustic impedances in order to establish this system as a novel way for ultrasonic applications. This paper provides experimental results about how is the ultrasonic signal affected in several acoustic impedances such as water, conductive gel, grease, jelly, and some animal grease with two methodologies, the first one using as transmitter and receiver a piezoelectric ceramic, and the second one using as receiver a PVDF polymer. Furthermore, provides a description of the design and construction of the ultrasonic system focused in the construction of the piezoelectric ceramic based transducer. Finally, the results are expressed in a comparative board in order to show the different behaviors between the two systems and to determinate which environment is better for these transducers
