This book presents the basis of Poincare plot and focus especially on traditional and new methods for analysing the geometry, temporal and spatial dynamics disclosed by the Poincare plot to evaluate heart rate variability (HRV).

Healthcare sensor networks (HSNs) now offer the possibility to continuously monitor human activity and physiological signals in a mobile environment. Such sensor networks may be able to reduce the strain on the present healthcare workforce by providing new autonomous monitoring services ranging from simple user-reminder systems to more advanced monitoring agents for preventive, diagnostic, and rehabilitative purposes. Potential services include reminding people to take their medication, providing early warning for the onset of heart attacks or epileptic seizures, and monitoring a childΓÇÖs physical activity in order to assess their growth and mental development. Healthcare Sensor Networks: Challenges Toward Practical Implementation discusses the fundamental concepts in designing and building such networks. It presents the latest developments in HSNs, explores applications of the technology, and provides insights into practical design and deployment challenges. Bringing together contributions from international experts in the field, the book highlights the key areas that require further research for HSNs to become a technological and commercially viable reality. The first part of the book concentrates on the engineering challenges, covering new biosensors, energy harvesting techniques, new wireless communication methods, and novel security approaches. Building from single sensing devices to networked sensing systems, the second part of the book looks at various health applications of HSNs. It addresses the human-centric requirements that should be considered in the design of HSN technologiesΓÇöcost, portability, functionality, and user acceptanceΓÇöand demonstrates how engineering compromises must be made in HSN solutions.A useful and timely resource for researchers, postgraduate students, and engineers looking for innovative solutions in healthcare, this book will also be of interest to medical and allied he

From network deployment to secure monitoring, this book addresses the latest developments in healthcare sensor networks¿medical monitoring devices implanted on the body or in the surrounding infrastructure. The text discusses fundamental concepts and provides examples of clinical applications, including sensors to monitor physical activity in children and wearable gait assistants for people with Parkinson¿s. Each chapter details a separate challenge in design and implementation. Addressing topics ranging from sensor hardware and the demand for higher data bandwidth to portability and cost, the book highlights the key areas that require further research for HSNs to become a technological and commercially viable reality.
