= Ultrasonic transducer
{wiki=Ultrasonic_transducer}
An ultrasonic transducer is a device that converts electrical energy into ultrasonic waves (high-frequency sound waves typically above 20 kHz) and vice versa. These transducers are employed in a variety of applications, including medical imaging (like ultrasound), industrial non-destructive testing, cleaning, and distance measurement. \#\#\# Key Components: 1. **Piezoelectric Material**: Most ultrasonic transducers utilize piezoelectric materials, which generate an electric charge in response to mechanical stress.
