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.}, keywords = {Piezopolymeric Transducer, Ultrasonic Sensorial Systems, Ultrasounds}, isbn = {1-4244-0755-9}, doi = {10.1109/ISIE.2007.4374816}, url = {http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=\&arnumber=4374816\&isnumber=4374555}, attachments = {https://geintra-uah.org/en/system/files/piezopolymeric.pdf}, author = {Ana Jimenez and {\'A}lvaro Hern{\'a}ndez and Ure{\~n}a, J. and J.J.
