Abstract

Recent research has shown that it is possible to utilize contact electrification combined with electrostatic induction to harvest electrical energy from the mechanical motion of air bubbles sliding along a charged solid surface immersed in water. The working principle of these devices is simple, but the design is usually complicated as transduction efficiency depends on a number of interdependent parameters. Here we propose a simple analytical model and demonstrate how it can be used to determine the optimal energy per bubble for a given resistive load. The model allows one to estimate the optimal energy harvested per bubble in terms of polymer thickness, electrode separation and load resistance. It is shown that the model provides a good fit to experimental data. The model may be used as an initial step when designing energy harvesting devices utilizing air bubbles sliding along a solid surface.

设计利用气泡沿浸入水中的氟聚合物滑动的电能收集装置

最近的研究表明，可以利用接触电化结合静电感应，从气泡沿浸入水中的带电固体表面滑动的机械运动中获取电能。这些装置的工作原理很简单，但设计通常比较复杂，因为传导效率取决于许多相互依赖的参数。在此，我们提出了一个简单的分析模型，并演示了如何利用该模型确定给定电阻负载下每个气泡的最佳能量。通过该模型，我们可以根据聚合物厚度、电极间距和负载电阻估算出每个气泡的最佳能量。实验表明，该模型与实验数据拟合良好。在利用沿固体表面滑动的气泡设计能量收集装置时，该模型可作为第一步。

期刊介绍： Smart Materials and Structures (SMS) is a multi-disciplinary engineering journal that explores the creation and utilization of novel forms of transduction. It is a leading journal in the area of smart materials and structures, publishing the most important results from different regions of the world, largely from Asia, Europe and North America. The results may be as disparate as the development of new materials and active composite systems, derived using theoretical predictions to complex structural systems, which generate new capabilities by incorporating enabling new smart material transducers. The theoretical predictions are usually accompanied with experimental verification, characterizing the performance of new structures and devices. These systems are examined from the nanoscale to the macroscopic. SMS has a Board of Associate Editors who are specialists in a multitude of areas, ensuring that reviews are fast, fair and performed by experts in all sub-disciplines of smart materials, systems and structures. A smart material is defined as any material that is capable of being controlled such that its response and properties change under a stimulus. A smart structure or system is capable of reacting to stimuli or the environment in a prescribed manner. SMS is committed to understanding, expanding and dissemination of knowledge in this subject matter.
