Application Cases

Experiment Name: Application of High-Voltage Power Amplifier in Electro-Actuation Experiments of Electroactive Polymers

Research Direction: Materials Science

Experimental Content: Observe the deformation of the material by applying voltage and frequency across the EAP material.

Test Objective: Verify the correlation between driving voltage/frequency and the deformation of the EAP material.

Testing Equipment: Signal generator, ATA-7010 High-Voltage Power Amplifier, one piece of 50mm × 50mm aluminum foil, fixtures.

Experimental Procedure:

As shown in the figure above, the experimental platform for the electroactive polymer actuation system includes: a signal generator to produce the signal; an Aigtek ATA-7010 high-voltage power amplifier to amplify the output signal from the signal generator; a 50mm × 50mm piece of aluminum foil; and fixtures to hold the material.

First, cut two 10mm × 10mm pieces and two 50mm × 5mm strips from the aluminum foil. Place these aluminum pieces on both sides of the EAP material to serve as媒介 (媒介, media) for the excitation voltage. Then, use the fixtures to secure the aluminum pieces and the EAP material. Subsequently, apply a gradually increasing voltage from 100V to 1000V at frequencies of 100 MHz, 300 MHz, 500 MHz, 1 Hz, and 2 Hz, respectively.

Experimental Results:
It was found that when the driving frequency was below 1 Hz, the EAP material did not deform. When the frequency reached 1 Hz, as the voltage increased above 800V, the material exhibited slight deformation. When the driving frequency was 2 Hz, slight deformation occurred at 300V, and the material deformation became more pronounced as the voltage continued to increase.
