This book presents the most important aspects of analysis of
dynamical processes taking place on the human body surface. It
provides an overview of the major devices that act as a prevention
measure to boost a person's motivation for physical activity. A
short overview of the most popular MEMS sensors for biomedical
applications is given. The development and validation of a
multi-level computational model that combines mathematical models
of an accelerometer and reduced human body surface tissue is
presented. Subsequently, results of finite element analysis are
used together with experimental data to evaluate rheological
properties of not only human skin but skeletal joints as well.
Methodology of development of MOEMS displacement-pressure sensor
and adaptation for real-time biological information monitoring,
namely "ex vivo" and "in vitro" blood pulse type analysis, is
described. Fundamental and conciliatory investigations, achieved
knowledge and scientific experience about biologically adaptive
multifunctional nanocomposite materials, their properties and
synthesis compatibility, periodical microstructures, which may be
used in various optical components for modern, productive sensors'
formation technologies and their application in medicine, pharmacy
industries and environmental monitoring, are presented and
analyzed. This book also is aimed at research and development of
vibrational energy harvester, which would convert ambient kinetic
energy into electrical energy by means of the impact-type
piezoelectric transducer. The book proposes possible prototypes of
devices for non-invasive real-time artery pulse measurements and
micro energy harvesting.
This book presents a guide to digital twin technologies and their
applications within manufacturing. It examines key technological
advances in the area of Industry 4.0, including numerical and
experimental models and the Internet of Things (IoT), and explores
their potential technical benefits through real-world application
examples. This book presents digital models of advanced
manufacturing processes dynamics that enable to control the cutting
processes including experimental and simulation studies for
brittle-ductile transition of ultra-precision machining materials
assuring product quality. Innovative electrical power harvesting
solutions from tool vibrations and wireless data transmission from
confined and heavily cooled environment are also included. It
explains the benefits of virtual and physical twins adapted to real
systems, including the ability to shorten the product's path to the
market, and enabling the transition to higher value-added
manufacturing processes. Including numerous illustrations and clear
solved problems, this book will be of interest to researchers and
industry professionals in the fields of mechatronics, manufacturing
engineering, computational mechanics.
In recent years microelectromechanical systems (MEMS) have emerged
as a new technology with enormous application potential. MEMS
manufacturing techniques are essentially the same as those used in
the semiconductor industry, therefore they can be produced in large
quantities at low cost. The added benefits of lightweight,
miniature size and low energy consumption make MEMS
commercialization very attractive. Modeling and simulation is an
indispensable tool in the process of studying these new dynamic
phenomena, development of new microdevices and improvement of the
existing designs. MEMS technology is inherently multidisciplinary
since operation of microdevices involves interaction of several
energy domains of different physical nature, for example,
mechanical, fluidic and electric forces. Dynamic behavior of
contact-type electrostatic microactuators, such as a microswitches,
is determined by nonlinear fluidic-structural,
electrostatic-structural and vibro-impact interactions. The latter
is particularly important: Therefore it is crucial to develop
accurate computational models for numerical analysis of the
aforementioned interactions in order to better understand
coupled-field effects, study important system dynamic
characteristics and thereby formulate guidelines for the
development of more reliable microdevices with enhanced
performance, reliability and functionality.
