Abstract
Description
Technical Field

[0002] With the changes and iterative updates of electrofluidic printing technology scenarios, the requirements for the printing and flow characteristics of the ink itself are becoming increasingly higher. Currently, general scenarios can only be matched with specific inks for printing.
[0003] Electrofluid printing technology controls the flow of printing ink by controlling the intensity and direction of the electric field.

Often, a good power amplifier is required to control signal transmission throughout the process. However, in actual operation, it is difficult for the needle / nozzle controlled by this power amplifier to achieve the desired spraying effect, especially when encountering problems such as a narrow process window and a long spraying time. It is difficult to deal with problems such as multiple needle drops, long drops, and continuous spraying caused by signal deviations during the working process, resulting in poor printing results.
