    Resumen

    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 used as a broadband
    ultrasonic transducer, in order to improve performances in
    ultrasonic sensorial systems, where the emission encoding with
    binary sequences, and the used modulation schemes, require
    considerably large bandwidth.
