Magnetic hybrid-materials multi-scale modelling, synthesis, and applications by Stefan Odenbach( )

1 edition published in 2021 in English and held by 137 WorldCat member libraries worldwide

Externally tunable properties allow for new applications of magnetic hybrid materials containing magnetic micro- and nanoparticles in sensors and actuators in technical and medical applications. By means of easy to generate and control magnetic fields, changes of the internal particle arrangements and the macroscopic properties can be achieved. This monograph delivers the latest insights into multi-scale modelling, experimental characterization, manufacturing and application of those magnetic hybrid materials

This book presents various questions of continuum mechanical modeling in the context of experimental and numerical methods, in particular, multi-field problems that go beyond the standard models of continuum mechanics. In addition, it discusses dynamic problems and practical solutions in the field of numerical methods. It focuses on continuum mechanics, which is often overlooked in the traditional division of mechanics into statics, strength of materials and kinetics. The book is dedicated to Prof. Volker Ulbricht, who passed away on April 9, 2021

Investigation of Multi Wall Carbon Nanotubes and Nanotube assemblies by a molecular mechanics approach( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Abstract The present work describes the modeling techniques applied for the investigation of assemblies of Carbon Nanotubes (CNTs) and Multi Wall Carbon Nanotubes (MWNTs). Motivated from possible future applications, for instance in new composite materials, the investigations of the interaction behavior of individual Carbon Nanotubes within an assembly of Carbon Nanotubes is mandatory in order to understand the behavior of larger scale structures made from CNTs, e.g. Carbon Nanotube fibers. The present research applies the Lennard-Jones potential for modeling the van-der-Waals interaction occurring between the nanotubes realizing the interaction behavior. The individual Carbon Nanotubes within the assembly are assumed to be rigid. All van-der-Waals bonds are taken into account in order to calculate an overall potential surface describing the behavior of the investigated structure. An example consisting of a Multi Wall Carbon Nanotube made of three armchair Single Wall Carbon Nanotubes (SWNTs) is investigated (with and without additional outer force) with respect to equilibrium positions of the structure.

Smart control of a soft robotic hand prosthesis by Astrid Rubiano Fonseca( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

The target of this thesis disertation is to develop a new Smart control of a soft robotic hand prosthesis for the soft robotic hand prosthesis called ProMain Hand, which is characterized by:(i) flexible interaction with grasped object, (ii) and friendly-intuitive interaction between human and robot hand. Flexible interaction results from the synergies between rigid bodies and soft bodies, and actuation mechanism. The ProMain hand has three fingers, each one is equipped with three phalanges: proximal, medial and distal. The proximal and medial are built with rigid bodies,and the distal is fabricated using a deformable material. The soft distal phalange has a new smart force sensor, which was created with the aim to detect contact and force in the fingertip, facilitating the control of the hand. The friendly intuitive human-hand interaction is developed to facilitate the hand utilization. The human-hand interaction is driven by a controller that uses the superficial electromyographic signals measured in the forearm employing a wearable device. The wearable device called MyoArmband is placed around the forearm near the elbow joint. Based on the signals transmitted by the wearable device, the beginning of the movement is automatically detected, analyzing entropy behavior of the EMG signals through artificial intelligence. Then, three selected grasping gesture are recognized with the following methodology: (i) learning patients entropy patterns from electromyographic signals captured during the execution of selected grasping gesture, (ii) performing a support vector machine classifier, using raw entropy data extracted in real time from electromyographic signals
Adjustable fluid and particle permeation through hydrogel composite membranes( )

in English and held by 1 WorldCat member library worldwide

Membranes act as smart structures in respect to their permeation abilities. Control of particle and fluid permeation through a synthetic membrane can be achieved by using different effects like size-exclusion or electromagnetic interactions that occur between the particles and membrane pores. The simulation of controlled permeability provides an insight into the smart behavior of membranes for chemical signal processing, sensing interfaces or lab-on-a-chip devices. In the current work, we model the underlying physical processes on a microfluidic level using the engineer's approach of laminar flow through pipes. Different pore geometries inside a composite membrane system consisting of a polyethylene terephthalate support membrane and a poly(N-isopropylacrylamide) hydrogel-layer are investigated. Simulations for different states of thermally induced pore opening are performed for free and blocked states. From the results we derive paradigms for the design of a membrane system for microfluidic cell-size profiling considering stimulus-range, pore shape and measurement setup

Le thème central de cette thèse est la conception d'actionneurs doux à partir de matériaux intelligents et d'une prothèse de main robotique souple. Notre approche prends en compte les différents points qui peuvent influer sur le développement d'une stratégie d'actionnement ou d'un muscle artificiel : i) Les mécanismes et la fonctionnalité de la main humaine afin d'identifier les exigences fonctionnelles pour une prothèse de main robotique en matière de préhension. ii) L'analyse et l'amélioration des mécanismes de la main robotique pour intégrer un comportement souple dans la prothèse. iii) L'évaluation expérimentale de la prothèse de main robotique afin d'identifier les spécifications du système d'actionnement nécessaire au fonctionnement cinématique et dynamique du robot. iv) Le développement et la modélisation d'une stratégie d'actionnement utilisant des matériaux intelligents.Ces points sont abordés successivement dans les 4 chapitres de cette thèse1. Analyse du mouvement de la main humaine pour l'identification des exigences technologiques pour la prothèse de main robotique.2. Conception et modélisation de la prothèse de main robotique à comportement souple.3. Evaluation mécatronique de la prothèse de main.4.

Modeling and simulation of hydrogels for the application as finger grippers( )

in English and held by 1 WorldCat member library worldwide

A chemo-electro-mechanical continuum model developed previously by the authors is utilized in this article to simulate electrically driven hydrogels for the application as finger grippers. To that end, a system consisting of an anionic gel and a cationic gel immersed in NaCl solution bath is discretized and numerically solved. An electric field is then applied between two electrodes on top and bottom of the simulation domain. For the numerical treatment of this study, the finite element method is exploited. By gradual increase in the electric potential between the two electrodes, the bending movement of the gels is realized. The process leading to bending of the gels is elaborated in detail in this article. It is concluded that our approach proves to be a practical tool for simulation of the closing and opening mechanism of a finger gripper stimulated by electric field
