This book was released on 2023-08-07 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electronic skin (E-skin) has gained significant attention due to its potential applications in the Internet of Things (IoT), artificial intelligence (AI), and flexible multi-sensing systems. Mimicking human skin, e-skin sensing devices can be employed in various scenarios. Among the most important sensing elements for tactile e-skin sensors are pressure and temperature sensors, which have increasingly garnered research interest over the past few decades. However, the design and fabrication of advanced pressure and temperature sensors can be challenging owing to complications such as signal interference, complex mechanism integration, and structural design issues. This review provides an overview of flexible pressure and temperature sensors used in e-skin, covering four main perspectives: material selection, mechanism integration, structural design, and manufacturing methods. The materials of different elements in the entire sensing system are comprehensively discussed, along with single and compound mechanisms of pressure and temperature sensing. Pressure and temperature sensors are divided into two types based on their electric output signals, which are exemplified in detail. The manufacturing methods used to fabricate these sensors, including printing methods, are outlined. Lastly, a summary of the future challenges faced by flexible pressure and temperature sensors used in e-skin is presented.

Book excerpt: The natural biological skin's sensor performance presents tremendous challenges to emulate on artificial, electronic systems. High sensitivity, stretchability, and self-repair are salient characteristics of natural skin that, if re-created on artificial electronic skins can empower robotics, wearable devices, and biomedical applications. Organic materials that are inherently soft, flexible, or elastic are useful starting materials to use for artificial electronic skins. In this thesis, we explore the use of soft, elastic rubber as building blocks for force/pressure sensors. In particular, we developed highly sensitive capacitive pressure sensors, and in combination with organic semiconductors, created the first pressure-sensitive organic field effect transistors with unprecedented sensitivity and speed. Our sensors can detect static pressures as small as 3 Pa with milisecond response times. We performed finite element modeling to understand how the shapes of the elastic rubber impacts mechanical sensitivity, and describe the use of soft lithography techniques as a scalable means of manufacturing such elastic shapes. We further developed such organic field effect pressure sensors on flexible substrates that can be integrated onto smart bandages to monitor the human pulse when placed on the radial artery near the wrist. To enable stretchable pressure sensors, we developed a technique to create surface buckling of carbon nanotubes. The buckled nanotube films are highly stretchable and transparent, achieving greater than 2,200 S/cm and stretchable up to 150% strains. In addition, we demonstrate the first repeatably self-healing electronic skin using a supramolecular organic-inorganic composite. We developed the self-healing material using a composite approach, and achieved a conductivity as high as 40 S/cm. The composite material is mechanically flexible, and is capable of sensing tactile and flexion forces. Lastly, we propose using organic transistors to build oscillatory circuits that respond to pressure in a similar fashion to that of biological touch receptors. We call our system Digital Tactile Sensors (DiTACTS). The DiTACT prototype sensor generates a frequency of about 0 - 200 Hz, with the frequency being proportional to the pressure applied. Thus, DiTACTS encodes pressure information using frequency encoding, similar to that of slow-adapting biological touch receptors.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Flexible Electronics for Neurological Electronic Skin with Multiple Sensing Modalities written by Haochuan Wan and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of electronic skin (E-skin) technology in the past decade has resulted in a great variety of flexible electronic devices that mimic the physical and chemical sensing properties of skin for applications in advanced robotics, prosthetics, and health monitoring technologies. The further advancement of E-skin technology demands closer imitation of skin receptors' transduction mechanisms, simultaneous detection of multiple information from different sources, and the study of transmission, processing and memory of the signals among the neurons. Motivated by such demands, this thesis focuses on design, fabrication, characterization of novel flexible electronic devices and integration of individual devices to realize prototype biomimetic E-skin with neurological and multimodal sensing functions. More specifically, we have studied flexible carbon nanotube thin-film transistors (CNT-TFTs) as control and signal processing units of E-skin and flexible ferroelectret nanogenerator (FENG) and triboelectric nanogenerator (TENG) as skin mechanoreceptors. Multiple fabrication methods, such as low-cost printing and conventional cleanroom-based microfabrication have been implemented to fabricate flexible CNT-TFTs with different structures and functions, especially the synaptic functions. Based on the research on individual devices, we have demonstrated a prototype force-sensing flexible neurological E-skin and its sensory nerve and synapse, with FENG serving as the sensory mechanoreceptor that generates action potentials (pulsed voltages) to be processed and transmitted by the flexible synaptic CNT-TFT. It allows for instantaneous detection of force stimuli and offers biological synapse-like behavior to store the stimulus information and relay the stimulus signals to the next stage. The force-sensing neurological E-skin was further augmented with visual and auditory sensing modalities by introducing phototransistor-based optical sensor and FENG-based acoustic sensor. Successful transduction of visual, auditory and tactile stimuli and synaptic processing and memory of those signals have all been demonstrated. Thanks to the multimodal sensing capability of the neurological E-skin, psychological associative learning experiment-"Pavlov's dog's experiment", was also successfully implemented electronically by synergizing actual visual and auditory signals in the synaptic transistor. Flexible electronics and prototype neurological E-skin system demonstrated in this thesis may offer an entry into novel multimodal, user-environment interactive soft E-skin system for soft robotic and diagnostic applications.

Download or read book Development Testing and Characterization of Electronic Skins for Robots written by Ritvij Sahasrabuddhe and published by . This book was released on 2016 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of this thesis is to test and characterize newly developed pressure sensors integrated into robot skin and understand their behavior for different testing parameters such as sensor and skin materials and geometry. Flexible electronic skin is meant to behave similar to human skin acting as a tactile interface with the robot environment. Before placing electronic skin onto robots, it is important to test and characterize such structures. Since the behavior of our pressure sensors embedded in robot skin was still unknown, an experimental setup has been developed in order to test and characterize the sensors and collect the real time data. The experimental setup described in this thesis includes various hardware systems such as a National Instrument's cRIO real time controller, a load cell and a plunger attached to a linear actuator to gathers the real time pressure measurements. The test process was automated using custom software written in LabVIEW which not only gathers the data in real time but also increases the speed of operation. Different force control algorithms were implemented, which safely achieve the robot-environment interaction. Along with the sensors, different skin types were tested and characterized based on the experimental data gathered from the system. After data analysis, a particular combination of skins and sensors was chosen as most promising for further studies.
