Our proposal is focused on part 3: ¿preparation and 4: ¿characterization of the priority program SPP 1165: ¿Nanowires and Nanotubes . Our main target is the investigation of mechamcal properties of nanowires, their coupling to electronic sensor structures äs transducers and the realization of a nanoelectromechanical biomimetic demonstrator. For that purpose, a universal applicable set of tools for the mechanical characterisation of nanowires shall be developed, independent on their fabrication, their geometry and the used materials. Technologies will be developed to align the nanowires and to couple them to an appropriate transducer. Initially the elastic properties of clamped nanowires will be analyzed. The main part of the investigations will be performed on resonant structures. Both well defined double clamped and randomly distributed single clamped nanowires will be investigated. The basic parameters of resonant structures resonant frequency and quality factors are used to extract Young s modulus, internal strain the influence of defects, adsorbates and the interaction with the environment. In addition, adsorption, stability and elastic properties will be investigated using nonresonant nanowires. With the extracted information a basic module for novel nanowire based nanoelectromechanical devices will be designed. This System will combine the piezo- and pyroelectric properties of group Ill-nitrides with the mechamcal specifics of nanowires. A demonstrator for the flow velocities in microfluidic Systems will be focused on. Perspectively, the proposed nanowirebased demonstrator is suitable for a variety of biocompatible biomimetic sensors, e.g. for acceleration and rotary motion.

我们的建议集中于第3部分：准备工作和4：»优先计划SPP 1165：»纳米线和纳米管的表征。我们的主要目标是纳米线的机械性能的投资，它们与电子传感器结构传感器的耦合以及实现纳米电机力学仿生示威者的实现。为此，应开发一套通用的用于纳米线机械表征的工具，独立于其制造，其几何形状和二手材料。将开发技术来对齐纳米线并将它们搭配到适当的传感器。最初，将分析夹紧纳米线的弹性特性。投资的主要部分将在共振结构上进行。定义良好的双夹具和随机分布的单夹具纳米线将进行研究。共振结构的基本参数使用共振频率和质量因子来提取年轻的模量，内部应变缺陷，吸附物以及与环境的相互作用。另外，将使用非共振纳米线研究吸附，稳定性和弹性特性。借助提取的信息，将设计一个基于纳米电极的新型纳米机电设备的基本模块。该系统将结合核酸基团的压电和高电特性与纳米线的机甲细节。将重点关注微流体系统中流速度的演示器。从透视上，拟议的基于纳米线的演示器适用于多种生物相容性的仿生传感器，例如用于加速和旋转运动。
