Sound sources based on dielectric elastomers

其目的是开发基于DE的声源概念，它充分利用其特性，具有更高的效率、更好的功能集成、更高的设计通用性、更好的功率和尺寸调整选项以及与传统系统相比显著减轻重量，从而扩大声源的应用范围。此外，还有放弃使用稀土、压电陶瓷甚至金属的可能性。这包括以下任务：-基于组合模拟法(网络描述和有限元方法)的DE-声源的计算机辅助设计和模拟方法-DE-声源的材料和工艺要求的基本原理，并深入了解对其行为的化学、技术和结构影响-为选定的应用开发声源-实现和检验这些声源作为技术示范以说明其潜力目的是为了深入了解DE-声源的全部潜力。通过这个项目，我们的目标是为基于DE的声源特别是动态DE致动器的发展提供新的动力。

The aim is to develop concepts for sound sources based on DE, which utilizes their properties to the full potential and feature greater efficiency, better functional integration, higher design versatility, better power- and size scaling options and significant weight reduction compared to conventional systems and thus extend the application range of sound sources. In addition, there is the possibility to forgo the use of rare earth, piezo ceramics and even metals. This includes the following tasks:- Computer aided design and simulation methodology of DE-sound sources based on the method of the Combined Simulation (Network Description and Finite Element Method)- Fundamentals of material and process requirements of DE-sound sources, with in depth understanding of the chemical, technological and structural influences on their behavior - Development of sound sources for selected applications- Realization and examination of these sound sources as technological Demonstrators to illustrate the potentialThe aim is to establish an in depth understanding of the full potential of DE-sound sources. With this project we aim to give new impetus to the development of DE based sound sources in particular and dynamical DE-actuators in general.
