Abstract
The actual fluid form of an electrolyte in a molecular electronic converter is an important factor that causes a decrease in the accuracy of a molecular electronic transducer (MET) liquid motion sensor. To study the actual fluid morphology of an inertial electrolyte in molecular electron transducers, an inlet effect is defined according to the fluid morphology of turbulent-laminar flow, and a numerical simulation model of turbulent-laminar flow is proposed. Based on the turbulent-laminar flow model, this paper studies the variation of the inlet effect intensity when the thickness of the outermost insulating layer is 50 µm and 100 µm, respectively. Meanwhile, the changes of the inlet effect intensity and the error rate of central axial velocity field are also analyzed when the input signal intensity is different. Through the numerical experiment, it verifies that the thickness of the outermost insulating layer and the amplitude of the input signal are two important factors which can affect the inlet effect intensity and also the accuracy of the MET. Therefore, this study can provide a theoretical basis for the quantitative study on the performance optimization of a MET liquid sensor.

Summary
Solid-state accelerometers are widely employed in many fields. The high frequency response of solid “inertia sensor” is better compared to that of the low-frequency domain [1]. A laminar flow model was established to study the flow signal of a single-channel electrolyte, and an ideal output signal was used for simulation; the impact. The single channel model in the sensitive chip is usually simulated, and the electrolyte flow mode in the channel is considered as laminar flow Based on this assumption, the output signal and other characteristics of the sensor can be better represented, the model can’t entirely express the multi-channel coupling effect in the turbulent-laminar flow mode. The output signal and other characteristics of the sensor can be better represented, the model can’t entirely express the multi-channel coupling effect in the turbulent-laminar flow mode To solve this problem, a multi-channel model of MET is proposed; this model can better describe turbulent and laminar flow patterns than the single-channel model. This paper qualitatively analyzes the two main factors that cause the intensity of the inlet effect, and their impact on the accuracy of the sensor
