The Application of the ATA-2000 Series High-Voltage Amplifiers in the Suspension of Polyethylene Spheres Based on Ultrasonic Technology

Author:Aigtek Number:0 Date:2025-08-27

Ultrasound standing wave levitation is an important means of non-contact and container-free processing. The principle is to use the radiating end of an ultrasonic transducer to produce high-frequency piston vibration, forming a sound field in the medium. By placing a reflective end on the sound wave transmission path, the sound wave is reflected back and superimposed with the incident sound wave to form a strong standing wave sound field. Objects placed in the standing wave sound field will reach a levitation state under the action of the radiated sound pressure. It is widely used in chemical synthesis, biological research, drug production, etc.

Antai Electronics offers a wide range of high-voltage amplifiers, which are widely used in ultrasonic testing fields and can be matched with suitable power amplifiers according to different transducer electrical parameters.

Experiment Name: Suspension of Polyethylene Spheres Based on Ultrasonic Technology

Experiment Principle: The radiating end of an ultrasonic transducer generates high-frequency piston vibration, forming a sound field in the medium. A reflective end is placed on the sound wave transmission path, causing the sound wave to reflect back and superimpose with the incident sound wave, forming a strong standing wave sound field. Objects placed in the standing wave sound field will reach a levitation state under the action of the radiated sound pressure.

Experiment Process:

The ultrasound standing wave levitation test system mainly consists of a signal generator, power amplifier, ultrasonic transducer, mechanical support device, and ultrasonic transducer.

A function signal generator produces specific periodic waveforms to provide electrical signals of various frequencies for the ultrasonic transducer. The signal is amplified by the ATA-2032 high-voltage amplifier to drive the ultrasonic transducer. According to the inverse piezoelectric effect, the transducer converts the electrical signal into a high-frequency sound signal. The sound signal superimposes multiple times with the reflective end to form a standing wave, thereby levitating the object.

Application Directions: Chemical synthesis, biological research, drug production

Application Scenarios: Microelectronics precision processing, non-contact manipulation of micro-biological samples, physical and chemical experiments without gravity effects
