The project aims are (A) to investigate soft magnetic hybrid materials consisting of magnetic particles suspended in a highly elastic matrix, which is partly or wholly made of thermoplastic components, and (B) to exploit the advantages of their magnetically reversibly changeable properties in prototype solutions for soft robotic applications.The visionary goal of the investigations is on enabling adaptive mechanical compliance of technical functional elements, such as compliant actuators and structures. It pursues the idea that by using these ‘intelligent’ materials, the performance of compliant systems can be significantly improved in comparison to systems without reversibly changeable mechanical properties. The focus of the proposed investigations is the consideration of the applicability of three material systems in context of soft material robotic systems and their comparative analysis and examination. Magnetic hybrid materials (1) with a thermoplastic elastomer as matrix material, (2) with an elastomer-thermoplastic matrix and (3) with an elastomer matrix and embedded macroscopic thermoplastic inserts will be studied. The emphasis of the first application period lies on the development of methods belonging to the theoretical description of the macroscopic mechanical behavior by providing suitable material models and design tools at different levels of abstraction. This includes experimental characterization of the mechanical material properties with respect to the special features of these materials, such as thermally or magnetically induced stiffness change.The systematic investigations consisting of material, component and system designs make it possible to find principal application possibilities of such magnetic hybrid materials and enable their targeted use for soft material robotic systems. The intrinsic presence of actuator and sensor capabilities of these material systems implemented with a high level of functional integration can lead to novel and potential grades in the adaptability of soft robotic systems to operational tasks and environmental conditions.

该项目的目标是(A)研究由悬浮在高弹性矩阵中的磁性颗粒组成的软磁混合材料，该材料部分或全部由热塑性部件制成，以及(B)在软机器人应用的原型解决方案中利用其磁性可逆变化特性的优势。研究的远景目标是实现技术功能元件的自适应机械顺应性，例如顺应致动器和结构。它追求的理念是，通过使用这些“智能”材料，与没有可逆可变机械性能的系统相比，兼容系统的性能可以显着提高。提出的研究重点是考虑三种材料系统在软材料机器人系统中的适用性，并对其进行比较分析和检查。将研究以热塑性弹性体为基体材料的磁性杂化材料(1)、弹性体-热塑性基体的磁性杂化材料(2)和弹性体基体与嵌入宏观热塑性嵌套的磁性杂化材料(3)。第一个应用阶段的重点是通过提供合适的材料模型和不同抽象层次的设计工具，发展属于宏观力学行为理论描述的方法。这包括与这些材料的特殊特征相关的机械材料性能的实验表征，例如热或磁诱导的刚度变化。由材料、部件和系统设计组成的系统研究使得找到这种磁性混合材料的主要应用可能性成为可能，并使其能够有针对性地用于软材料机器人系统。这些具有高水平功能集成的材料系统的执行器和传感器功能的内在存在可以导致软机器人系统对操作任务和环境条件的适应性的新颖和潜在等级。
