The aim of the project is the investigation of the use of hybrid materials in technical actuator systems and the implementation of their beneficial properties in prototypes for locomotion and manipulation purposes. These hybrid materials are composed of magnetic particles as suspended component and complex substrates with or without reversible variable properties. In the focus is the use of compliant magnetic hybrid materials based on elastomers as matrix material. The reversible variable mechanical behaviour of technical functional elements should be realized and specifically controlled by magnetic fields using particle matrix interactions. On this basis, the realization of - adaptive actuator systems with on the current load state and ambient characteristics adaptable mechanical behaviour, as well as - sensors with variable sensitivity integrated in locomotion and manipulation systems is planned. In the field of manipulation systems, work is continuing steadily with studies of the immediate contact area between the object which is to be gripped and the effector (gripper). Based on the promising results of the preliminary investigations in the first funding period, the planned work of the second application period will be particularly focused on sensor applications integrated in actuator systems. The current objective comprises the model-based theoretical and experimental metrological investigation of two kinds of magnetic hybrid materials: electrically conductive hybrid magnetic materials and magnetic hybrid materials with an elastomer thermoplastic matrix. The use of magneto-sensitive hybrid materials allows the realization of sensor and actuator systems with a complex and on the current operating situation independently adaptive and adaptable mechanical behaviour. From the perspective of an engineer who is focused on the generation of technical solutions, properties which are only achievable through the systematic integration of the particles in the matrix and their interactions are: - the ability to easily create complex deformations by appropriate shaping of the objects and the design of the magnetic fields - a reversible variable, by magnetic fields controllable, mechanical compliance - a reversible variable, by magnetic fields controllable anisotropy of mechanical properties and parameters - the dependence of the mechanical properties of the load history and the ambient parameters. Based on own preliminary work in the first application period, the goal in the, for the applicant new application field of sensor technology, is the realization of force / acceleration sensors with controllable sensitivity through magnetic fields resulting from particle-matrix interactions.
