Hydrogels are a fascinating class of polymers which show an immense ability of swelling under the influence of temperature, pH value or concentrations of different species in aqueous solutions. The volume change can amount up to several hundred percent. This unique behaviour is already used in such applications like disposable diapers, contact lenses or drug-delivery systems. The ability to perform mechanical work has been shifted the technical interest more and more towards sensors and actuators exploiting the thermo-chemo-mechano-electrical coupling within hydrogels. The accuracy requirements for such devices are much more demanding than for previous applications. Therefore, a deep knowledge of both the material and the functional properties of hydrogel sensors and actuators is needed. The monograph describes state of the art and recent developments for these materials in sensor and actuator technology.

LIG is a revolutionary technique that uses a common CO2 infrared laser scriber, like the one used in any machine shop, for the direct conversion of polymers into porous graphene under ambient conditions. This technique combines the preparation and patterning of 3D graphene in a single step, without the use of wet chemicals. The ease in the structural engineering and excellent mechanical properties of the 3D graphene obtained have made LIG a versatile technique for applications across many fields. This book compiles cutting-edge research on LIG by different research groups all over the world. It discusses the strategies that have been developed to synthesize and engineer graphene, including controlling its properties such as porosity, composition, and surface characteristics. The authors are pioneers in the discovery and development of LIG and the book will appeal to anyone involved in nanotechnology, chemistry, environmental sciences, and device development, especially those with an interest in the synthesis and applications of graphene-based materials.

Download Bioinspired Sensing, Actuation, and Control in Underwater Soft Robotic Systems Book in PDF, ePub and Kindle
This book includes representative research from the state‐of‐the‐art in the emerging field of soft robotics, with a special focus on bioinspired soft robotics for underwater applications. Topics include novel materials, sensors, actuators, and system design for distributed estimation and control of soft robotic appendages inspired by the octopus and seastar. It summarizes the latest findings in an emerging field of bioinspired soft robotics for the underwater domain, primarily drawing from (but not limited to) an ongoing research program in bioinspired autonomous systems sponsored by the Office of Naval Research. The program has stimulated cross‐disciplinary research in biology, material science, computational mechanics, and systems and control for the purpose of creating novel robotic appendages for maritime applications. The book collects recent results in this area.

Download Actuators and Their Applications Book in PDF, ePub and Kindle
As demand has increased for new types of equipment that are more suited to the ever-evolving world of industry, demand for both new and traditional types of actuators has soared. From automotive and aeronautical to biomedical and robotics, engineers are constantly developing actuating devices that are adapted to their particular needs in their particular field, and actuators are used in almost every field of engineering that there is. This volume not only lays out the fundamentals of actuators, such as how they operate, the different kinds, and their various applications, but it also informs the engineer or student about the new actuators that are being developed and the state-of-the-art of actuators. Edited and written by highly experienced and well-respected engineers with a deep understanding of their subject, there is no other volume on actuators that is more current or comprehensive. Whether as a guide for the latest innovations in actuators, a refresher reference work for the veteran engineer, or an introductory text for the engineering student, this is a must-have for any engineer’s or university’s library. Covering the theory and the practical applications, this breakthrough volume is a “one stop shop” for any engineer or student interested in actuators.

Download Hydrogels Book in PDF, ePub and Kindle
Hydrogels are crosslinked, macromolecular polymeric materials arranged in a three-dimensional network, which can absorb and retain large amounts of water. Hydrogels are commonly used in clinical practice and experimental medicine for a wide range of applications, including drug delivery, tissue engineering and regenerative medicine, diagnostics, cellular immobilization, separation of biomolecules or cells, and barrier materials to regulate biological adhesions. This book elucidates the underlying concepts and emerging applications of hydrogels and will provide key case studies and critical analysis of the existing research.

Download Plasma Polymerized Hydrogel Thin Films for Applications in Sensors and Actuators Book in PDF, ePub and Kindle
Plasma polymerization was used to produce thermoresponsive, hydrogel films of N-Isopropylacrylamide (NIPAAm) in a single step. Through variation of reactor conditions such as deposition pressure and substrate temperature, physicochemical properties of the hydrogel films such as crosslink density and thus swelling could be controlled. Chemical bonding structures in plasma polymerized NIPAAm were studied using Fourier transform infrared spectroscopy (FTIR). Contact angle goniometry and quartz crystal microbalance with dissipation monitoring were used to confirm the existence of a hydrophilic-hydrophobic transition in plasma polymerized NIPAAm thin films, analogous to the lower critical solution temperature (LCST) transition in linear, uncrosslinked chains. Hydrogen bonding in NIPAAm thin films was found to control the moisture uptake capacity; films prepared at higher substrate temperatures and lower reactor pressures, and hence believed to possess greater crosslink density, showed the highest moisture uptake capacity in ambient humidity. Free volume characteristics of NIPAAm thin films were studied using Doppler broadening energy spectroscopy (DBES). Furthermore, a novel, electrophoretic procedure was conceived to incorporate biomolecules such as antibodies in plasma polymerized NIPAAm films for use as sensing layers in vapor phase, surface acoustic wave sensors.

Download Holographic Sensors Book in PDF, ePub and Kindle
This thesis presents a theoretical and experimental approach for the rapid fabrication, optimization and testing of holographic sensors for the quantification of pH, organic solvents, metal cations, and glucose in solutions. Developing non-invasive and reusable diagnostics sensors that can be easily manufactured will support the monitoring of high-risk individuals in any clinical or point-of-care setting. Sensor fabrication approaches outlined include silver-halide chemistry, laser ablation and photopolymerization. The sensors employ off-axis Bragg diffraction gratings of ordered silver nanoparticles and localized refractive index changes in poly (2-hydroxyethyl methacrylate) and polyacrylamide films. The sensors exhibited reversible Bragg peak shifts, and diffracted the spectrum of narrow-band light over the wavelength range λpeak ≈ 495-1100 nm. Clinical trials of glucose sensors in the urine samples of diabetic patients demonstrated that they offer superior performance compared to commercial high-throughput urinalysis devices. Lastly, a generic smartphone application to quantify colorimetric tests was developed and tested for both Android and iOS operating systems. The sensing platform and smartphone application may have implications for the development of low-cost, reusable and equipment-free point-of-care diagnostic devices.
