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.</style></abstract><num-vols><style face="normal" font="default" size="100%">1</style></num-vols></record></records></xml>
