Abstract: This paper presents a prototype of an ultrasonic transducer based on electromechanical film (EMFi). This electromechanical film provides a wide bandwidth response, useful for robotic applications. Furthermore, its sensitivity is constant enough to allow echo-pulse measurement in the desired frequency range. The emission patterns are obtained for different configurations, verifying the correspondence between experimental data and theoretical piston-like model. Results suggest that the polymer can be suitably us…
