The controlled movement of dry particles using non-mechanical means is desirable in a number of different applications, including solar panel dust mitigation, toner particle motion and in the handling and beneficiation of regolith for In-Situ Resource Utilization (ISRU). The electric curtain, the electrostatic traveling wave (ETW) and the electro-dynamic screen (EDS) are examples of techniques that can transport and separate particles with no moving parts nor fluid medium. This review paper brings together the research carried out on these techniques.

We provide a comprehensive review on the particle movement mechanisms and the development and application of ETW methods, featuring a diverse range of hardware and circuitry, particulate material and process objectives. We focus on the evaluation of experimental development in the area of dust mitigation, particle transport and ISRU processes. We also detail the current knowledge about theory and modelling methods. Moreover, we provide a guide for possible improvement of the effectiveness of ETW devices, by outlining the limitations in application, theoretical understanding and potential research aspects.

在许多不同的应用中，都需要使用非机械方式控制干颗粒的运动，包括太阳能电池板的粉尘缓解、碳粉颗粒运动以及用于原位资源利用 (ISRU) 的风化层的处理和选矿。电动窗帘、静电行波 (ETW) 和电动屏幕 (EDS) 是可以在没有移动部件或流体介质的情况下传输和分离粒子的技术示例。这篇评论论文汇集了对这些技术进行的研究。

我们对粒子运动机制以及 ETW 方法的开发和应用进行了全面审查，包括各种硬件和电路、粒子材料和工艺目标。我们专注于评估粉尘缓解、粒子传输和 ISRU 过程领域的实验发展。我们还详细介绍了有关理论和建模方法的当前知识。此外，我们通过概述应用、理论理解和潜在研究方面的局限性，为可能改进 ETW 设备的有效性提供了指导。
