Book Description
Wearable sensors help us in taking corrective steps that will make us healthier than yesterday. Wearable sensors empower people to be productive, active and attentive by instilling in them, the need to take care of themselves. Now, smart phone users can monitor their health and fitness on their mobile devices. Smart watches, performance monitoring, virtual coaching, body temperature management, activity tracking are few applications worth mentioning. A continuous estimation of fitness level, employing these wearable devices, can potentially help users in setting personalized short and long-term exercise goals leading to positive impact on one's overall health. Efficiency, life span, power consumption and performance are among the key issues in desiring a wearable device. Where a device needs longer life, bigger battery can be used but large size leads to discomfort in wearable sensors usage, so we concentrate on smaller sized batteries and smaller devices. Smaller the size of wearable sensor goes; bigger the longevity problem arises in terms of maintaining the power to use wearable sensor efficiently. Bluetooth used as a wireless link communication between wearable sensor and handheld devices or computer drains wearable device power faster. In this context prolonging battery life is one among major challenges that needs to be addressed in a wearable system. In this study, we address various efficient power management techniques for wearable sensors and decisions taken during designing a software algorithm, since software is also one among key factors that drives the hardware of a wearable sensor. This thesis is organized as follows: first, the wearable sensor hardware and firmware are described. Next, power management techniques, provided by the manufacturer are presented. Finally, power budget analysis and efficient power management methods are illustrated with results. Chapter 1 details the importance of wearable sensor and uses in variety of fields.

Book Description
This book describes power management integrated circuits (PMIC), for power converters and voltage regulators necessary for energy efficient and small form factor systems. The authors discuss state-of-the-art PMICs not only for battery powered wearable devices, but also energy harvesting-based devices. The circuits presented support voltage scaling to reduce the overall average power consumption of a wearable device, resulting in longer device operating time. The discussion includes many designs, control techniques and approaches to distribute efficiently the power among different blocks in the device. • Demonstrates for readers how to innovate in designing power management integrated circuits (PMIC) suitable for wearable devices, powered by either battery or harvesting energy; • Introduces a dual outputs switched capacitor, using a single voltage regulator to minimize the area overhead and discusses the effect of having more than two outputs on the area and power efficiency; • Introduces a novel clock-less digital LDO regulator that eliminates the use of the clocked comparator and serial shift register in the conventional design; • Presents experimental results of energy harvesting-based power management units (PMU), using different combinations of power converters and voltage regulators, providing a guide for designers to select the appropriate option based on device requirements.

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.

Book Description
Biosensors and systems in the form of wearables and “nearables” (i.e., everyday sensorized objects with transmitting capabilities such as smartphones) are rapidly evolving for use in healthcare. Unlike conventional approaches, these technologies can enable seamless or on-demand physiological monitoring, anytime and anywhere. Such monitoring can help transform healthcare from the current reactive, one-size-fits-all, hospital-centered approach into a future proactive, personalized, decentralized structure. Wearable and nearable biosensors and systems have been made possible through integrated innovations in sensor design, electronics, data transmission, power management, and signal processing. Although much progress has been made in this field, many open challenges for the scientific community remain, especially for those applications requiring high accuracy. This book contains the 12 papers that constituted a recent Special Issue of Sensors sharing the same title. The aim of the initiative was to provide a collection of state-of-the-art investigations on wearables and nearables, in order to stimulate technological advances and the use of the technology to benefit healthcare. The topics covered by the book offer both depth and breadth pertaining to wearable and nearable technology. They include new biosensors and data transmission techniques, studies on accelerometers, signal processing, and cardiovascular monitoring, clinical applications, and validation of commercial devices.
