Special Issue Information

Dear Colleagues,

Wireless body sensors for health monitoring have a tremendous potential in the remote management of health. This includes both the monitoring of patients, where the sensor applications can save lives by predicting health status exacerbations and raise alarms in dangerous situations, and health trend monitoring of healthy people to provide support for a healthier lifestyle. The development, production, and marketing of m-Health-related medical devices and services is one of the most promising future economic and social issues, as it is already well-accepted that remote health monitoring can improve health and reduce overall healthcare costs significantly. Further developments are expected in developing new, accessible, smaller, and more energy-efficient medical devices –wireless body sensors—for data acquisition, as well as in advanced automatic data analysis and the generation of personalized diagnoses and possible personalized treatment of different health conditions, which is the main requirement for personalized medicine. The amount of medical data has increased rapidly in the past decade, with expectations of its further exponential increase in the next decade. In addition to clinical data, personal biomedical data will be produced by various sensors in real-time and through long periods of time. Analyses of the generated Big Data, supported by artificial intelligence and deep learning methods, will result in new medical knowledge that can be used in healthcare. To accommodate the data coming from the huge numbers of biomedical sensors, new data management and processing algorithms and structures need to be developed that will manage the data on all levels from sensors, personal computing devices, and computer clouds.

This Special Issue expects innovative work to explore new frontiers and challenges in the field of body sensors technology, interconnections, applications, services, and social impacts. Prospective authors are cordially invited to submit their original contributions related to various aspects of wireless body sensors.

The recent trend in electrocardiogram (ECG) device development is towards wireless body sensors applied for patient monitoring. The ultimate goal is to develop a multi-functional body sensor that will provide synchronized vital bio-signs of the monitored user. In this paper, we present an ECG sensor for long-term monitoring, which measures the surface potential difference between proximal electrodes near the heart, called differential ECG lead or differential lead, in short. The sensor has been certified as a class IIa medical device and is available on the market under the trademark Savvy ECG. An improvement from the user’s perspective—immediate access to the measured data—is also implemented into the design. With appropriate placement of the device on the chest, a very clear distinction of all electrocardiographic waves can be achieved, allowing for ECG recording of high quality, sufficient for medical analysis. Experimental results that elucidate the measurements from a differential lead regarding sensors’ position, the impact of artifacts, and potential diagnostic value, are shown. We demonstrate the sensors’ potential by presenting results from its various areas of application: medicine, sports, veterinary, and some new fields of investigation, like hearth rate variability biofeedback assessment and biometric authentication.

Immersive virtual reality has recently developed into a readily available system that allows for full-body tracking. Can this affordable system be used for component tracking to advance or replace expensive kinematic systems for motion analysis in the clinic? The aim of this study was to assess the accuracy of position and orientation measures from Vive wireless body trackers when compared to Vicon optoelectronic tracked markers attached to (1) a robot simulating trunk flexion and rotation by repeatedly moving to know locations, and (2) healthy adults playing virtual reality games necessitating significant trunk displacements. The comparison of both systems showed component tracking with Vive trackers is accurate within 0.68 ± 0.32 cm translationally and 1.64 ± 0.18° rotationally when compared with a three-dimensional motion capture system. No significant differences between Vive trackers and Vicon systems were found suggesting the Vive wireless sensors can be used to accurately track joint motion for clinical and research data.

In recent years there has been an increasing need for miniature, low-cost, commercially accessible, and user-friendly sensor solutions for wireless body area networks (WBAN), which has led to the adoption of new physical communication interfaces providing distinctive advantages over traditional wireless technologies. Ultra-wideband (UWB) and intrabody communication (IBC) have been the subject of intensive research in recent years due to their promising characteristics as means for short-range, low-power, and low-data-rate wireless interfaces for interconnection of various sensors and devices placed on, inside, or in the close vicinity of the human body. The need for safe and standardized solutions has resulted in the development of two relevant standards, IEEE 802.15.4 (for UWB) and IEEE 802.15.6 (for UWB and IBC), respectively. This paper presents an in-depth overview of recent studies and advances in the field of application of UWB and IBC technologies for wireless body sensor communication systems. Full article

The use of wearable body sensors for health monitoring is a quickly growing field with the potential of offering a reliable means for clinical and remote health management. This includes both real-time monitoring and health trend monitoring with the aim to detect/predict health deterioration and also to act as a prevention tool. The aim of this systematic review was to provide a qualitative synthesis of studies using wearable body sensors for health monitoring. The synthesis and analysis have pointed out a number of shortcomings in prior research. Major shortcomings are demonstrated by the majority of the studies adopting an observational research design, too small sample sizes, poorly presented, and/or non-representative participant demographics (i.e., age, gender, patient/healthy). These aspects need to be considered in future research work. Full article
