"Tailoring Actuation Properties of\r\nThermoresponsive Hydrogels and\r\nImplementation into Soft Robotic\r\nApplications"^^ . "Soft material robotics relies on the development of responsive, soft materials and\r\nrequires high standards, with respect to the material properties: High responsivity,\r\nrobust mechanical properties, high cycle times, and fast responses are some\r\nexamples for these requirements, which are rarely found in such responsive, soft\r\nmaterials, and thus need to be adjusted by material engineering.\r\nThis thesis addresses tailoring the properties of thermoresponsive hydrogels and\r\nimplementing these materials into soft robotic applications. Furthermore, a thorough\r\ninvestigation of material responsivity and mechanical properties is conducted,\r\nwhich are crucial parameters for the development of soft actuators.\r\nFirst, a template-assisted fabrication method based on sacrificial zinc oxide templates\r\nis introduced, which yields microporous and highly thermoresponsive hydrogels.\r\nCompared to its conventional bulk counterpart, this material exhibits a\r\nlarge volume transition and generates considerable stroke forces upon stimulation,\r\nwhich are crucial requirements for actuator applications. These changes in thermoresponsive\r\nactuation properties result from the increased surface area created\r\nby the microporosity of the hydrogel. Actuation capabilities are demonstrated on\r\nthe basis of a soft, thermally controlled gripper.\r\nBased on the previous findings, two-photon 3D laser printing is used to fabricate\r\nresponsive hydrogel microactuators with precise control of actuator surfaceto-\r\nvolume ratio and to investigate actuation capabilities as a function of actuator\r\ndesign and fabrication parameters. It turns out that miniaturization of the actuators\r\nand especially the surface-to-volume-ratio have a major impact on responsivity.\r\nIn addition, variation of the processing parameters during fabrication is\r\nfound to be a facile strategy for tailoring actuator properties, such as stiffness and\r\nresponsivity. Moreover, the assembly of individual actuators into microactuator\r\nsystems, enables cooperative functions, such as capturing and releasing cargo in a\r\nmicrofluidic chip upon thermal stimulation.\r\nThe micro engineering strategies presented in this work, provide a toolkit for\r\nunderstanding the science of thermo-actuation and tailoring actuation properties\r\nof responsive hydrogels. Furthermore, methods for developing soft robotic applications\r\nat the microscale using such hydrogels are demonstrated."^^ . "2024" . . . . . . . "Tobias"^^ . "Spratte"^^ .
