Special Issue Information

Dear Colleagues,

Micro/nano sensors and actuators have the advantage of having a simple structure, high accuracy, and good reliability, and are widely used in current precision instruments and equipment. Due to the fact that micro/nano sensors and actuators belong to MEMS systems, they are different from traditional general sensors and actuators and require higher precision manufacturing, design, simulation, experimental testing, etc. Generally, micro/nano sensors and actuators use functional materials to create driving and sensing components. In addition, for micro/nano sensors and actuators, research needs to be carried out based on specific application requirements. When conducting theoretical analysis, it is also necessary to consider the coupling problem caused by micro size, which does not necessarily need to be considered for general large size sensors and actuators. Accordingly, this Special Issue seeks to showcase research papers, communications, and review articles that focus on novel methodological developments in micro/nano sensors and actuators, i.e., on novel process chains, including novel structures, manufacturing, systems, controlling methods and applications.

We look forward to receiving your submissions!

The inkjet printing technology based on piezoelectric micro-jets can effectively realize the efficient and high-precision processing of special-shaped structures. In this work, a nozzle-driven piezoelectric micro-jet device is proposed, and its structure and micro-jet process are described. ANSYS two-phase, two-way fluid–structure coupling simulation analysis is carried out, and the mechanism of the piezoelectric micro-jet is described in detail. The effects of voltage amplitude, input signal frequency, nozzle diameter and oil viscosity on the injection performance of the proposed device are studied, and a set of effective control methods is summarized. The correctness of the piezoelectric micro-jet mechanism and the feasibility of the proposed nozzle-driven piezoelectric micro-jet device are proved by experiments, and an injection performance test is carried out. The experimental results are consistent with the ANSYS simulation results, which confirms the correctness of the experiment. Finally, the stability and superiority of the proposed device are verified via comparation experiments. Full article
