In recent years, various technologies dedicated to the formation of micro- and nanostructures have been intensively developed. Moreover, the book presents a technology for replicating the geometry of the AAO membrane in a biocompatible chitosan membrane, when nanopillars are formed on the surface of the chitosan membrane.

This book takes a profound journey into the advancements, challenges, and potential applications of natural fiber hybrid composites, shaping the future of sustainable engineering solutions and innovative materials with advancements in natural fiber hybrid composites.

This book presents an innovative approach to the synthesis and mechanical characterization of hydroxyapatite (HA)-based nanocomposites for biotechnological applications. By integrating advanced X-ray diffraction (XRD) techniques with ultrasonic pulse-echo testing, it provides a high-precision method for determining nanocrystal size, stress-strain behavior, and elastic modulus. The book investigates the effects of doping HA with silver and copper iodide, enhancing structural integrity and bioactivity, and offering new perspectives for optimizing HA-based materials in biomedical applications.The book explores the investigation of nanocrystal size of natural HA using X-ray diffraction, as well as the evaluation of an innovative technique for measuring the modulus of elasticity related to the atomic density of planes in unit cell and super cells of crystal lattices. It also examines the relationship between Young’s modulus and planar density in unit cells, super cells (2×2×2), and symmetry cells of cubic crystal lattices. Furthermore, the book explores the effect of calcination temperature on the mechanical and photophysical properties of CuI-doped HA, providing a deeper understanding of material stability under varying conditions.By linking fundamental materials science with applied biomedical engineering, this book establishes a robust framework for the development of next-generation biomaterials. The combination of innovative synthesis techniques and advanced mechanical characterization offers practical insights to improve the longevity and performance of HA-based implants and scaffolds.This book will be a valuable resource for researchers, engineers, and professionals in materials science, nanotechnology, and biomedical engineering. It will particularly benefit those working with bioactive materials, implant development, and mechanical characterization, as it provides cutting-edge methods for optimizing HA composites for clinical use.

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.
