Application Cases

Ultrasound is a sound with a pitch higher than human hearing, exceeding 20 kHz in frequency, and has wide-ranging applications across many fields. Low-frequency ultrasound, as a method for rapidly enhancing various biological activities, has garnered increasing attention over the past decade. By adjusting ultrasound parameters, different physical, chemical, and biological effects can be achieved, thereby enhancing the activity of target cells.

The Aigtek ATA-100 series power amplifier can drive ultrasonic transducers to generate ultrasound and build testing platforms. It is capable of outputting stable arbitrary waveforms, making it suitable for driving ultrasonic transducers in a wider range of application scenarios.

Experiment Name: Study on the Effect of Ultrasound on the Growth and Development of Mung Bean Seeds

Experimental Principle:
When ultrasound acts on mung bean seeds, it causes vibrations in the cell membranes inside the seeds. This vibration helps increase the permeability of the cell membranes, promotes the exchange of substances inside and outside the cells, and thus accelerates the seed germination process. The cavitation effect of ultrasound generates tiny bubbles in the liquid, and the collapse of these bubbles produces powerful impact forces. When ultrasound acts on mung bean seeds, cavitation can increase the porosity of the seeds and even break the seed coat, thereby improving the seeds' water absorption capacity and oxygen uptake efficiency. Ultrasound can also affect the activity of enzymes inside mung bean seeds.

Experimental Procedure:
A signal generator was used to output signals at frequencies of 48 kHz, 65 kHz, and 85 kHz, which were amplified by the ATA-105B power amplifier to drive the ultrasonic transducer to generate ultrasound acting on mung bean seeds. Four groups of soaked, plump mung bean seeds were selected, with 30 seeds in each group. A control group without ultrasound stimulation served as the blank control, while experimental groups with ultrasound frequencies of 48 kHz, 65 kHz, and 85 kHz were established. The stimulation time for each group was 35 minutes, with a signal excitation voltage of 10 Vpp. Additionally, the ATA-105B can amplify arbitrary waveforms, allowing observation of the effects of different signal waveforms on mung bean growth.
