Book Description :

Tactile sensing aims to electronically capture physical attributes of an object via mechanical contact. It proves indispensable to many engineering tasks and systems, in areas ranging from manufacturing to medicine and autonomous robotics. Biological skin, which is highly compliant, is able to perform sensing under challenging and highly variable conditions with levels of performance that far exceed what is possible with conventional tactile sensors, which are normally fabricated with non-conforming materials. The development of stretchable, skin-like tactile sensors has, as a result, remained a longstanding goal of engineering. However, to date, artificial tactile sensors that might mimic both the mechanical and multimodal tactile sensory capabilities of biological skin remain far from realization, due to the challenges of fabricating spatially dense, mechanically robust, and compliant sensors in elastic media. Inspired by these demands, this dissertation addresses many aspects of the challenging problem of engineering skin-like electronic sensors. In the first part of the thesis, new methods for the design and fabrication of thin, highly deformable, high resolution tactile sensors are presented. The approach is based on a novel configuration of arrays of microfluidic channels embedded in thin elastomer membranes. To form electrodes, these channels are filled with a metal alloy, eutectic Gallium Indium, that remains liquid at room temperature. Using capacitance sensing techniques, this approach achieves sensing resolutions of 1 mm$^{-1}$. To fabricate these devices, an efficient and robust soft lithography method is introduced, based on a single step cast. An analytical model for the performance of these devices is derived from electrostatic theory and continuum mechanics, and is demonstrated to yield excellent agreement with measured performance. This part of the investigation identified fundamental limitations, in the form of nonmonotonic behavior at low strains, that is demonstrated to generically affect solid cast soft capacitive sensors. The next part of the thesis is an investigation of new methods for designing soft tactile sensors based on multi-layer heterogeneous 3D structures that combine active layers, containing embedded liquid metal electrodes, with passive and mechanically tunable layers, containing air cavities and micropillar geometric supports. In tandem with analytical and computational modeling, these methods are demonstrated to facilitate greater control over mechanical and electronic performance. A new soft lithography fabrication method is also presented, based on the casting, alignment, and fusion of multiple functional layers in a soft polymer substrate. Measurements indicate that the resulting devices achieve excellent performance specifications, and avoid the limiting nonmonotonic behavior identified in the first part of the thesis. In order to demonstrate the practical utility of the devices, we used them to perform dynamic two-dimensional tactile imaging under distributed indentation loads. The results reflect the excellent static and dynamic performance of these devices. The final part of the thesis investigates the utility of the tactile sensing methods pursued here for imaging lumps embedded in simulated tissue. In order to facilitate real-time sensing, an electronic system for fast, array based measurement of small, sub-picofarad (pF) capacitance levels was developed. Using this system, we demonstrated that it is possible to accurately capture strain images depicting small lumps embedded in simulated tissue with either an electronic imaging system or a sensor worn on the finger, supporting the viability of wearable sensors for tactile imaging in medicine. In conclusion, this dissertation confronts many of the most vexing problems arising in the pursuit of skin-like electronic sensors, including fundamental operating principles, structural and functional electronic design, mechanical and electronic modeling, fabrication, and applications to biomedical imaging. The thesis also contributes knowledge needed to enable applications of tactile sensing in medicine, an area that has served as a key source of motivation for this work, and aims to facilitate other applications in areas such as manufacturing, robotics, and consumer electronics.

Book Description :

This thesis proposes an effective methodology for enhancing the perceptual capabilities and achieving interaction control of the iCub humanoid robot. The method is based on the integration of measurements from different sensors (force/torque, inertial and tactile sensors) distributed along the robot’s kinematic chain. Humanoid robots require a substantial amount of sensor information to create their own representations of the surrounding environment. Tactile perception is of primary importance for the exploration process. Also in humans, the tactile system is completely functional at birth. In humanoid robotics, the measurements of forces and torques that the robot exchanges with its surroundings are essential for safe interaction with the environment and with humans. The approach proposed in this thesis can successfully enhance the perceptual capabilities of robots by exploiting only a limited number of both localized and distributed sensors, providing a feasible and convenient solution for achieving active compliance control of humanoid robots.

Book Description :

This book describes some devices that are commonly identified as tactile or force sensors. This is achieved with different degrees of detail, in a unique and actual resource, through the description of different approaches to this type of sensors. Understanding the design and the working principles of the sensors described here requires a multidisciplinary background of electrical engineering, mechanical engineering, physics, biology, etc. An attempt has been made to place side by side the most pertinent information in order to reach a more productive reading not only for professionals dedicated to the design of tactile sensors, but also for all other sensor users, as for example, in the field of robotics. The latest technologies presented in this book are more focused on information readout and processing: as new materials, micro and sub-micro sensors are available, wireless transmission and processing of the sensorial information, as well as some innovative methodologies for obtaining and interpreting tactile information are also strongly evolving.

Ionic polymer metal composites (IPMCs) can generate a voltage when physically deformed. Conversely, an applied small voltage or electrical field can induce an array of spectacular large deformation or actuation behaviours in IPMCs, such as bending, twisting, rolling, twirling, steering and undulating. An important smart material, IPMCs have applications in energy harvesting and as self-powered strain or deformation sensors, they are especially suitable for monitoring the shape of dynamic structures. Other uses include soft actuation applications and as a material for biomimetic robotic soft artificial muscles in industrial and medical contexts. This comprehensive volume on ionic polymer metal composites provides a broad coverage of the state of the art and recent advances in the field written by some of the world’s leading experts on various characterizations and modeling of IPMCs. Topics covered in this two volume set include uses in electrochemically active electrodes, electric energy storage devices, soft biomimetic robotics artificial muscles, multiphysics modeling of IPMCs, biomedical applications, IPMCs as dexterous manipulators and tactile sensors for minimally invasive robotic surgery, self-sensing, miniature pumps for drug delivery, IPMC snake-like robots, IPMC microgrippers for microorganisms manipulations, Graphene-based IPMCs and cellulose-based IPMCs or electroactive paper actuators (EAPap). Edited by the leading authority on IMPCs, the broad coverage will appeal to researchers from chemistry, materials, engineering, physics and medical communities interested in both the material and its applications.

Book Description :

Future robots are expected to work closely and interact safely with real-world objects and humans alike. Sense of touch is important in this context, as it helps estimate properties such as shape, texture, hardness, material type and many more; provides action related information, such as slip detection; and helps carrying out actions such as rolling an object between fingers without dropping it. This book presents an in-depth description of the solutions available for gathering tactile data, obtaining aforementioned tactile information from the data and effectively using the same in various robotic tasks. The efforts during last four decades or so have yielded a wide spectrum of tactile sensing technologies and engineered solutions for both intrinsic and extrinsic touch sensors. Nowadays, new materials and structures are being explored for obtaining robotic skin with physical features like bendable, conformable, and stretchable. Such features are important for covering various body parts of robots or 3D surfaces. Nonetheless, there exist many more hardware, software and application related issues that must be considered to make tactile sensing an effective component of future robotic platforms. This book presents an in-depth analysis of various system related issues and presents the trade-offs one may face while developing an effective tactile sensing system. For this purpose, human touch sensing has also been explored. The design hints coming out of the investigations into human sense of touch can be useful in improving the effectiveness of tactile sensory modality in robotics and other machines. Better integration of tactile sensors on a robot’s body is prerequisite for the effective utilization of tactile data. The concept of semiconductor devices based sensors is an interesting one, as it allows compact and fast tactile sensing systems with capabilities such as human-like spatio-temporal resolution. This book presents a comprehensive description of semiconductor devices based tactile sensing. In particular, novel Piezo Oxide Semiconductor Field Effect Transistor (POSFET) based approach for high resolution tactile sensing has been discussed in detail. Finally, the extension of semiconductors devices based sensors concept to large and flexile areas has been discussed for obtaining robotic or electronic skin. With its multidisciplinary scope, this book is suitable for graduate students and researchers coming from diverse areas such robotics (bio-robots, humanoids, rehabilitation etc.), applied materials, humans touch sensing, electronics, microsystems, and instrumentation. To better explain the concepts the text is supported by large number of figures.

Book Description :

In this research work, a flexible polymer lab-on-a-tube integrated with spirally-rolled physical/biochemical microsensors and microfluidic devices has been designed, fabricated and characterized for in situ measuring physiological/metabolic data and enhanced drug delivery in a catheter application. This new approach provides a unique way to assemble multiple microsensors and microfluidic devices both inside and outside the flexible polymer tube using standard microfabrication methods, while avoiding most challenging wiring and assembling problems associated with previous methods. Furthermore, this new tube-type platform maintains catheter inherent lumen potency for in situ drug delivery or inserting medical tools through it. In realizing the flexible polymer lab-on-a-tube for a smart catheter, first, a new spirally-rolled tube-type platform has been developed and characterized. It has been aimed to develop a new functional 'catheter' with required dimension, axial, flexural and torsional rigidities for various applications, and also works as a platform to mount multiple microsensors and microfluidic devices. This spirally-rolled polymer tube can be easily assembled at the tip of the conventional microcatheters due to its structural affinity or work as a free-standing catheter. As functional components of the spirally-rolled polymer tube, flexible physical and biochemical microsensors on the Kapton film, flexible tactile sensors based on PVDF-TrFE piezoelectric copolymer, and flexible Parylene microchannels, which are embedded in the tube wall, have been successfully fabricated and characterized. Flexible temperature sensor (RTD), flow rate sensor (hot film anemometry), oxygen biosensor (amperometric sensor) and glucose biosensor (amperometric sensor) have been fabricated and fully integrated both inside and outside the spirally-rolled polymer tubes with various diameters. The fabricated microsensors showed good performances not only in a planar configuration but also in a spirally-rolled configuration. To solve the visual and tactile limitations caused by the nature of catheterization, innovative bump and dome shape PVDF-TrFE films with different dimensions were successfully fabricated by a new mold transfer method and tested as flexible tactile sensors. PVDF-TrFE film works as a functional flexible substrate and developed tactile sensors have shown high sensitivity and strong mechanical strength for microcatheter applications. Flexible Parylene microchannels have been fabricated by a rapid and low cost stamp-and-stick fabrication method and successfully assembled on the polymer tube by spirally-rolling. This unique spiral structure with microchannels shows a potential capability as a basic component of the effective catheter-based drug delivery system. Two new models of flexible polymer lab-on-a-tube have been designed by combining flexible microsensors and microfluidic devices together in this work. Much more advanced and effective 'smart' catheter models have been demonstrated for cardiovascular disease and brain tumor monitoring and treatment. This flexible polymer lab-on-a-tube system provides a generic platform for developing patient-specific 'smart' microcatheters that incorporate with microsensors, microactuators, wireless signal communication modules and microfluidic devices tailored for the patient's unique condition.

Book Description :

From the Author's Preface Ceramic sensors have been in use for more than thirty years. Since ceramics exhibit a number of specific characteristics that enable their cost to become lower and their reliability to increase, they have occupied a significant position in sensor technology. This is why many companies and universities have directed their efforts towards investigating and developing new ceramic sensors and expanding their areas of application. To the best of our knowledge.., there [has been] no book treating different sensors on the basis of their common physical and chemical properties, technological principles, and applications. This book [is] a detailed survey of ceramic sensors and a generalization of the results achieved in this field so far. Ceramic sensors for different physical quantities are discussed without going too deep into theory... The concept of ceramic sensors includes all sensors that are produced using ceramic technology. It also covers thick film sensors, since from a structural and technological point of view, they can be regarded as a variety of ceramic sensors. The subject of scientific research in this book is humidity, gas. temperature, and pressure sensors on the basis of semiconductor and dielectric ceramic materials and solid electrolytes. Special attention is paid to the physical and chemical, as well as the technological, bases of ceramic sensors, their classification, the types of materials used... , the methods of controlling their parameters and characteristics, the areas of application, and the electric circuits for connecting the sensors.

Book Description :

Soft and bio-nanomaterials offer a tremendously rich behavior due to the diversity and tailorability of their structures. Built from polymers, nanoparticles, small and large molecules, peptoids and other nanoscale building blocks, such materials exhibit exciting functions, either intrinsically or through the engineering of their organization and combination of blocks. Thus, it is not surprising that a variety of challenges, for example, in energy storage, environment protection, advanced manufacturing, purification and healthcare, can be addressed using these materials. The recent advances in understanding the behavior of soft matter and biomaterials are being actively translated into functional materials systems and devices, which take advantages of newly discovered and specifically created morphologies with desired properties. This major reference work presents a detailed overview of recent research developments on fundamental and application-inspired aspects of soft and bio-nanomaterials and their emerging functions, and will be divided into four volumes: Vol 1: Soft Matter under Geometrical Confinement: From Fundamentals at Planar Surfaces and Interfaces to Functionalities of Nanoporous Materials; Vol 2: Polymers on the Nanoscale: Nano-structured Polymers and Their Applications; Vol 3: Bio-Inspired Nanomaterials: Nanomaterials Built from Biomolecules and Using Bio-derived Principles; Vol 4: Nanomedicine: Nanoscale Materials in Nano/Bio Medicine.
