Low-Cost Sensors and Biological Signals


Book Description

Many sensors are currently available at prices lower than USD 100 and cover a wide range of biological signals: motion, muscle activity, heart rate, etc. Such low-cost sensors have metrological features allowing them to be used in everyday life and clinical applications, where gold-standard material is both too expensive and time-consuming to be used. The selected papers present current applications of low-cost sensors in domains such as physiotherapy, rehabilitation, and affective technologies. The results cover various aspects of low-cost sensor technology from hardware design to software optimization.




Biomedical Signals and Sensors I


Book Description

This two-volume set focuses on the interface between physiologic mechanisms and diagnostic human engineering. Today numerous biomedical sensors are commonplace in clinical practice. The registered biosignals reflect mostly vital physiologic phenomena. In order to adequately apply biomedical sensors and reasonably interpret the corresponding biosignals, a proper understanding of the involved physiologic phenomena, their influence on the registered biosignals, and the technology behind the sensors is necessary. The first volume is devoted to the interface between physiologic mechanisms and arising biosignals, whereas the second volume is focussed on the interface between biosignals and biomedical sensors. The physiologic mechanisms behind the biosignals are described from the basic cellular level up to their advanced mutual coordination level during sleep. The arising biosignals are discussed within the scope of vital physiologic phenomena to foster their understanding and comprehensive analysis.

The Promise of New Technologies in an Age of New Health Challenges


Book Description

There is a changed emphasis in many health services, with conventional pressures such as budget and workforce constraints, combined with the indirect forces of social change and strategic direction, bringing about the need for more flexible approaches for the longer term. By enabling different care models and delivery channels, telehealth offers demonstrably effective and sustainable solutions for issues such as access to and quality of care. This book presents 18 papers delivered at the 5th Global Telehealth Conference, held in Auckland, New Zealand, in November 2016. The theme chosen for Global Telehealth 2016 is 'The Promise of New Technologies in an Age of New Health Challenges', and the papers included here cover a wide variety of topics, from theoretical and abstract contributions through to discussions of practical projects and highly specific applied contributions. The book also includes two invited papers which detail recent contributions to two global issues in which telehealth plays a major role: universal health coverage and personal health monitoring. With papers ranging in scope from computer assisted screening technology for diabetic retinopathy to behavior change through computer games, this book will be of interest to all those involved in the design and provision of healthcare services.




Biomedical Sensors


Book Description

Sensors are the eyes, ears, and more, of the modern engineered product or system- including the living human organism. This authoritative reference work, part of Momentum Press's new Sensors Technology series, edited by noted sensors expert, Dr. Joe Watson, will offer a complete review of all sensors and their associated instrumentation systems now commonly used in modern medicine. Readers will find invaluable data and guidance on a wide variety of sensors used in biomedical applications, from fluid flow sensors, to pressure sensors, to chemical analysis sensors. New developments in biomaterials- based sensors that mimic natural bio-systems will be covered as well. Also featured will be ample references throughout, along with a useful Glossary and symbols list, as well as convenient conversion tables.




Sensors and Sensing in Biology and Engineering


Book Description

Biological sensors are usually remarkably small, sensitive and efficient. It is highly desirable to design corresponding artificial sensors for scientific, industrial and commercial purposes. This book is designed to fill an urgent need for interdisciplinary exchange between biologists studying sensors in the natural world and engineers and physical scientists developing artificial sensors. The main topics cover mechanical sensors, e.g. waves and sounds, visual sensors and vision and chemosensors. Readers will obtain a fuller understanding of the nature and performance of natural sensors as well as enhanced appreciation for the current status and the potential applicability of artificial microsensors.




Real-Time Data Acquisition in Human Physiology


Book Description

Real-Time Data Acquisition in Human Physiology: Real-Time Acquisition, Processing, and Interpretation—A MATLAB-Based Approach focuses on the design and development of a computer-based system to detect and digitally process human ECG, EMG, and carotid pulse waveforms in real time.

Low-power Wearable Healthcare Sensors


Book Description

Advances in technology have produced a range of on-body sensors and smartwatches that can be used to monitor a wearer’s health with the objective to keep the user healthy. However, the real potential of such devices not only lies in monitoring but also in interactive communication with expert-system-based cloud services to offer personalized and real-time healthcare advice that will enable the user to manage their health and, over time, to reduce expensive hospital admissions. To meet this goal, the research challenges for the next generation of wearable healthcare devices include the need to offer a wide range of sensing, computing, communication, and human–computer interaction methods, all within a tiny device with limited resources and electrical power. This Special Issue presents a collection of six papers on a wide range of research developments that highlight the specific challenges in creating the next generation of low-power wearable healthcare sensors.




Sensor Systems for Biological Agent Attacks


Book Description

Over the last ten years, there has been growing concern about potential biological attacks on the nation's population and its military facilities. It is now possible to detect such attacks quickly enough to permit treatment of potential victims prior to the onset of symptoms. The capability to "detect to warn", that is in time to take action to minimize human exposure, however, is still lacking. To help achieve such a capability, the Defense Threat Reduction Agency (DTRA) asked the National Research Council (NRC) to assess the development path for "detect to warn" sensors systems. This report presents the results of this assessment including analysis of scenarios for protecting facilities, sensor requirements, and detection technologies and systems. Findings and recommendations are provided for the most probable path to achieve a detect-to-warn capability and potential technological breakthroughs that could accelerate its attainment.
