The objective of TP3 during the second phase of the project is the design, technology development and realization as well as the characterization of a technology-neutral, universal and highly miniaturized fatigue test platform in MEMS technology. This platform will serve for the systematic thermo-mechanical loading of bottom-up heterogeneously integrated nano-functional elements under realistic loads, including the effects of pressure, temperature and humidity. On the MEMS scale, this represents a completely new approach. First, the focus is on DEP self-assembled and micro-positioned CNTs, later other nanowires or nano membrane structures manufactured from Si, BN or Al are of interest.The second phase is consistently aiming at the newly emerging challenges of reliability assessment at the nano scale. To reach this goal, the cooperation with the TP1, 2, 4, 5, 6 and 8 is mandatory.AP1 includes the design for the development of the fatigue testing platform as well as the apparatus of the simulative and experimental methods for reliability assessment. The aim is the consistent integration and purely electrical control and readout of the individual MEMS components into a dynamic mechanical testing device which is capable of applying alternating and subcritical loads. Very important is the involvement of the other TP regarding technological integration, especially regarding the compatibility of the targeted nano-functional elements of the platform, combined with maximum universality of the testing platform itself. Key philosophy here is the "sample centric approach": The testing device may be build, if necessary, as a result of the MEMS processes, around the already assembled test specimen.AP2 bundles in cooperation with TP2, the development of design concepts, the optimization using FE simulation, used for the layout of the MEMS platform, and the integration of multi-scale models of molecular dynamics (TP1) into the design environment foreseen for fatigue analysis and description of failure mechanisms. Particularly important is the consideration of imperfections, such as defects and functional groups, but also the structure-property correlation and its dependence on processing, in particular with respect to interface properties. In addition, concepts for reliability assessment under the given loading conditions have to be developed.AP3 involves the development of technologies for the fatigue testing platform, the integration of the MEMS components and the testing of integrated nano-functional elements, provided by TP5, 6 and 8. In comparison to the 1st phase, more resources for technology development have to be planned, which allows the realization of all planned goals.AP4 aims at the experimental validation of the fatigue testing platform and the thermo-mechanical characterization of nano-functional elements compared to the simulations. Modern failureanalytical techniques, such as FIB, SEM and TEM are used to determine structure-property c.

项目第二阶段的TP 3目标是设计、技术开发和实现一个技术中立、通用和高度小型化的MEMS技术疲劳测试平台。该平台将用于自下而上异质集成纳米功能元件在实际负载下的系统热机械负载，包括压力，温度和湿度的影响。在MEMS规模上，这代表了一种全新的方法。第一阶段的重点是DEP自组装和微定位碳纳米管，随后是其他纳米线或纳米膜结构由Si，BN或Al制造的兴趣。第二阶段是一致的，旨在在纳米尺度上的可靠性评估的新出现的挑战。为了实现这一目标，与TP 1、2、4、5、6和8的合作是强制性的。AP 1包括疲劳试验平台的开发设计以及可靠性评估的模拟和实验方法的装置。其目的是将各个MEMS组件的一致集成和纯电气控制和读取集成到能够施加交变和亚临界负载的动态机械测试设备中。非常重要的是其他TP在技术集成方面的参与，特别是关于平台的目标纳米功能元件的兼容性，以及测试平台本身的最大通用性。这里的关键理念是“以样本为中心的方法”：如果需要的话，测试装置可以作为MEMS工艺的结果而围绕已经组装的测试封装来构建。AP 2束与TP 2合作，开发设计概念，使用FE仿真进行优化，用于MEMS平台的布局，以及将分子动力学（TP 1）的多尺度模型集成到设计环境中，以预测疲劳分析和失效机制的描述。特别重要的是考虑缺陷，如缺陷和官能团，但也结构-性能相关性及其对加工的依赖性，特别是相对于界面性能。此外，在给定的负载条件下的可靠性评估的概念必须开发。AP 3涉及疲劳测试平台的技术开发，MEMS组件的集成和集成纳米功能元件的测试，由TP 5，6和8提供。与第一阶段相比，必须计划更多的技术开发资源，这使得所有计划目标得以实现。AP 4旨在对疲劳测试平台进行实验验证，并与模拟相比，对纳米功能元件进行热机械表征。现代失效分析技术，如FIB、SEM和TEM，用于确定结构-性能参数。
