Description

technical field [0001] The invention relates to an electrostatic printing head, in particular to a near-field electrostatic printing head which can realize low-voltage driving and high-precision printing based on electro-hydraulic dynamics. Background technique [0002] Micro-nano patterned structure, device manufacturing and its application have become research hotspots in the international micro-nano field. Traditional MEMS silicon-based manufacturing processes (such as deposition, photolithography, and etching, etc.) are difficult to meet the low cost and large size (~m) of products based on micro-nano patterned structures due to their high manufacturing costs and harsh environmental requirements Manufacturing requirements greatly restrict the application range of micro-nano patterned products. For example, flexible electronics, as an emerging industry in my country in the future, requires low cost, large size and flexible substrates, but MEMS technology cannot be applied ...
