An '''ultrasonic transducer''' is a device that converts [[ultrasound]] to [[electricity|electrical]] signals, and vice versa. Many are composed of [[piezoelectricity|piezoelectric]] material, and can consist of one active element that produces sound waves, or several elements arranged in an [[array]]. Ultrasonic transducers are used in all artificial efforts to produce or detect ultrasound.
