Application Cases

Ultrasonic standing wave levitation is a crucial non-contact, container-free processing method. Compared to other non-contact techniques, ultrasonic standing wave levitation offers significant advantages such as the absence of heating effects and excellent levitation stability, making it highly promising for applications in mechanical manufacturing, biochemical trace analysis, droplet dynamics, and other fields.

Aigtek offers a wide range of high-voltage amplifier models, which are extensively used in ultrasonic testing applications. These amplifiers can be matched to different transducers based on their electrical parameters.

Experiment Name: Study on Ultrasonic Standing Wave Levitation and Directional Transport Methods

Experimental Principle:
Ultrasonic levitation is a technology that uses the force field generated by ultrasonic waves to suspend objects. The fundamental principle involves an ultrasonic vibrator (typically a piezoelectric ceramic transducer) emitting ultrasonic waves, which create high-frequency vibrations in the air. At specific frequencies, these vibrations can form a stable acoustic pressure field. When the acoustic field reaches sufficient intensity, small particles or lightweight objects can be levitated in the air under the influence of the acoustic pressure gradient force.

Experimental Procedure:
The ultrasonic standing wave levitation test system primarily consists of a signal generator, power amplifier, ultrasonic transducer, reflector, high-speed imaging measurement system, oscilloscope, and mechanical fixation support device.

A function signal generator produces specific periodic waveforms, providing electrical signals of various frequencies to the ultrasonic transducer. The signal is amplified by an ATA-2022B high-voltage amplifier to drive the ultrasonic transducer. Based on the inverse piezoelectric effect, the transducer converts the electrical signal into high-frequency acoustic signals. These acoustic signals superimpose multiple times with the reflector to form standing waves, enabling object levitation. During the experiment, a high-speed camera captures images of the levitated object.
