ultraäänipiezoelementin

An ultraäänipiezoelementti, commonly known as a piezoelectric transducer for ultrasound, is a device that converts electrical energy into mechanical vibrations (specifically ultrasonic waves) and vice versa. This effect is based on the piezoelectric property of certain materials, where mechanical stress produces an electric charge, and conversely, an applied electric field causes deformation.

These elements are typically constructed from ceramic materials like lead zirconate titanate (PZT) or from crystalline quartz. When an alternating voltage is applied across the electrodes of the piezoelectric element, it causes the material to vibrate at a high frequency, generating ultrasound waves. Conversely, when ultrasonic waves strike the element, they induce mechanical vibrations that generate an electrical voltage, allowing the element to act as a receiver.

Ultraäänipiezoelementit are fundamental components in a wide range of applications. In medical imaging, they are used in ultrasound probes to create detailed images of internal organs and tissues. In industrial settings, they are employed for non-destructive testing to detect flaws within materials, for cleaning applications to generate powerful cavitation, and for distance measurement using sonar principles. They are also found in scientific research for precise manipulation and sensing. The frequency of operation and the size of the element determine its specific application and performance characteristics.
