Abstract
(EN) The invention relates to a wave-emitting device comprising an electromechanical actuator stimulated by a signal generator that allows it to generate torsional waves with a higher amplitude, and to an ultrasonic transducer comprising said device. The use of said devices allows the reconstruction of the structural characteristics of the materials subjected to the waves generated by the emitter device.
(ES) La presente invención se refiere a un dispositivo para la emisión de ondas que comprende un actuador electromecánico estimulado por un generador de señales que le permite generar ondas de torsión con una mayor amplitud, así como a un transductor ultrasónico que comprende dicho dispositivo. El empleo de estos dispositivos permite la reconstrucción de las características estructurales de los materiales que se someten a las ondas generadas con el dispositivo emisor.
