Droplet-Based energy harvesting is one of the most recent techniques used to convert environmental mechanical energies into electrical energy. Despite unique properties like compatibility with MEMS fabrication and efficient performance in reduced spaces, their operation is limited by the negative effects of electrowetting. In presence of an external electric filed, the wetting state of a droplet can be a function of three factors: the properties of applied dielectric, the wettability features of the droplet, and the amount of applied electric filed. An appropriate circuit can manage the effect of external electric filed on the droplets which here is considered as a tool to mitigate the negative effects of electrowetting. This paper presents designing, modeling, and fabrication steps of a droplet-based power generator considering electrowetting during fabrication and evaluation processes. The generator operation was analyzed in a voltage-constrained circuit and the experimental data were in accordance with the proposed semi-empirical model in this regard. Generator evaluation was done using a range of capacities made by 12 to 84 droplets under frequencies of 0.8, 10.8, and 16.6 Hz and a bias voltage of 7.5 V. The maximum output voltage and power was obtained by applying 16.6 Hz frequency to 84 droplets, reaching 1.25 V and 1.56 μW, respectively.

基于液滴的能量收集是用于将环境机械能转换为电能的最新技术之一。尽管具有与MEMS制造的兼容性和在缩小的空间中的高效性能等独特的性能，但其操作受到电润湿的负面影响所限制。在存在外部电场的情况下，液滴的润湿状态可以是三个因素的函数：施加的电介质的性质，液滴的润湿性特征以及施加的电场的量。适当的电路可以管理外部电场对液滴的影响，在此将其视为减轻电润湿负面影响的工具。本文介绍了设计，建模，在制造和评估过程中考虑电润湿的基于液滴的发电机的制造和制造步骤。在电压约束电路中分析了发电机的运行，在这方面，实验数据与所提出的半经验模型相符。发生器评估是通过在0.8、10.8和16.6 Hz的频率以及7.5 V的偏置电压下由12到84个墨滴产生的一系列容量进行的。通过对84个墨滴施加16.6 Hz的频率可获得最大输出电压和功率，达到1.25 V和1.56μ W，分别。
