This open access book unveils groundbreaking advancements in non-invasive therapeutic technologies, focusing on the integration of digital twins and artificial intelligence to enhance circulatory health. At the heart of this book is the exploration of innovative solutions that promise to revolutionize medical practices and patient care.The chapters delve into critical topics such as ultrasonic and vibrational blood flow activation, acoustic activation of human circulatory parameters, and acoustofluidic separation of bioparticles. Readers will discover how low-frequency ultrasound can safely dissociate erythrocytes from aggregates, reduce blood pressure and improve blood gas metabolism within minutes, and manage pulmonary hypertension without medication. The book also highlights the development of smart devices like the "Vilim ball" for tremor therapy and other patented technologies aimed at improving blood flow in diabetic patients and those with mobility impairments.This essential volume is a must-read for researchers, clinicians, and practitioners in the fields of biomedical engineering, mechatronics, and healthcare technology. It offers invaluable insights into cutting-edge therapeutic strategies that are set to transform both clinical settings and home care environments.

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.
