Application Cases

Experiment Name: Pulsed Voltage-Driven Electrostatic Printing

Research Direction: Micro/Nano Circuit Printing

Experimental Content: Utilizing pulsed voltage amplified by a signal amplifier to drive the printing of micro/nano circuits.

Test Equipment: Signal generator, ATA-7015 high-voltage amplifier, 3D printer, etc.

Experimental Process:

Figure: Experimental setup for pulsed voltage-driven electrostatic printing

The output terminal of the signal generator was connected to the input terminal of the high-voltage amplifier. The positive output terminal of the high-voltage amplifier was connected to the print nozzle of the 3D printer, while the negative terminal was connected to the receiving substrate of the 3D printer and grounded. The signal generator generated pulsed square wave signals, which were amplified by the ATA-7015 high-voltage amplifier and applied to the print nozzle of the 3D printer. This drove the ejection of gold nanoparticle ink from the print nozzle, forming micron-sized printing droplets that were precisely deposited onto the surface of bioplastic fibers on the receiving substrate.

Experimental Results:

During the printing process, the 3D printer's built-in microscopic monitoring camera observed that, with the application of pulsed voltage and the movement of the receiving platform, the ejected gold nanoparticle ink deposited onto the surface of white bioplastic fibers, forming uniform black lines. Further observation under an electron microscope revealed that the gold nanoparticle ink was precisely deposited onto the center of the bioplastic fiber surface, forming micro-scale wires with a line width of approximately 4 μm.

Recommended Power Amplifier: ATA-7015
