BACKGROUND:
The Wriskwatch(tm) is a novel, watch-based pulse detection device that detects the loss of a radial pulse via advanced pulse detection technology and immediately contacts emergency medical systems.
OBJECTIVE:
We designed a first in man, prospective, single-blinded, phase I study to evaluate the ability of this device to detect motionlessness and pulselessness in human subjects as a simulation of sudden cardiac death.

PURPOSE
Automated systems able to infer detailed measures of a person’s social interactions and physical activities in their natural environments could lead to better understanding of factors influencing well-being. We assessed the feasibility of a wireless mobile device in measuring sociability and physical activity in older adults, and compared results with those of traditional questionnaires.

Older adults often struggle with maintaining self-aware of their ability to carry out everyday activities important for independence. Unobtrusive sensors embedded in the home can monitor how older adults interact with objects around the home and can provide objective accounts of behaviors to support self-awareness. In this paper, we describe the design and four month deployment of a prototype sensing system that tracks medication taking and phone use in the homes of two older adults.

Wearable sensors enable long-term continuous physiological monitoring, which is important for the treatment and management of many chronic illnesses, neurological disorders, and mental health issues. Examples include: diabetes, autism spectrum disorder (ASD), depression, drug addition, and anxiety disorders.

We measured the electrical activity signals of the heart through vital signs monitoring garments that have textile electrodes in conductive yarns while the subject is in stable and dynamic motion conditions. To measure the electrical activity signals of the heart during daily activities, four types of monitoring garment were proposed. Two experiments were carried out as follows: the first experiment sought to discover which garment led to the least displacement of the textile electrode from its originally intended location on the wearer’s body. In the second, we measured and compared the electrical activity signals of the heart between the wearer’s stable and dynamic motion states.

This work describes the implementation of a complete Wireless Body-Area Network (WBAN) system to deploy in medical environments. Issues related to hardware implementations, software and wireless protocol designs are addressed. In addition to reviewing and discussing the current attempts in wireless body area network technology, a WBAN system that has been designed for healthcare applications will be presented in detail herein. The wireless system in the WBAN uses medical bands to obtain physiological data from sensor nodes.

In recent years, because of the decline in birth-rate and the growth in the population of elderly people, the lack of doctors and the increase of the medical cost is becoming a big problem. One of solutions for this problem is to prevent the humans from contracting diseases in order to reduce the medical cost (e.g., by using the hospital as few times as possible). In this research, we have developed a wearable vital sensor which can be used anywhere without disrupting the everyday life of the patient.

The use of health-enabling technologies is regarded as one important means to face some of the challenges which accompany the demographic change with an expected rise in multi-morbidity and an increased need of care. A precondition for the sensible use of these technologies is their integration in existing information system structures, and – preferably – the enhancement of these into sensor-enhanced health information systems (seHIS). The aim of this review is to report on recent progress in seHIS, and thus to identify relevant areas of research that have to be addressed to provide patient-centered services in a semantically interoperable environment. A literature search in PubMed/Medline was combined with a manual search of papers (n = 1004) in three prominent health/medical informatics journals and one biomedical engineering journal starting from the year 2007. Despite a multitude of papers that present advanced systems using health-enabling technologies, only few papers could be identified that explicitly describe the design of seHIS or the integration of health-enabling technologies into health information systems. Recurring statements emphasise the importance of the following areas of research: patient-centered care using all available sources of information, data security, the stringent use of data representation and device connectivity standards, and adequate methods for data fusion and diagnostic analysis.

Tactile sensing is a developing technology and can be used for detecting parameters describing contact between surfaces. It is of growing application as the technology progresses with increased possibilities for automatic perception. In this chapter the potential of the distributive sensing approach is discussed for monitoring metrics, motion and behaviour in people through the outcome of a series of experimental applications. These illustrate the ability to extract descriptions as information, rather than data on metrics or motion. The method uses an approach of discrimination to determine parameters describing contact conditions or for recognising the nature of contact. Using this approach, the distributive deformation response of a surface detected at a few sensing points leads to a device of mechanical simplicity.

This volume contains the proceedings of the Twenty-second International Conference on Medical Informatics Europe MIE 2009, that was held in Sarajevo, Bosnia and Herzegovina, from 30 August to 2 September 2009. The scientific topics present in this proceedings range from national and trans-national eHealth roadmaps, health information and electronic health record systems, systems interoperability and communication standards, medical terminology and ontology approaches, and social networks to Web, Web 2.0, and Semantic Web solutions for patients, health personnel, and researchers. Furthermore, they include quality assurance and usability of medical informatics systems, specific disease management and telemedicine systems, including a section on devices and sensors, drug safety, clinical decision support and medical expert systems, clinical practice guidelines and protocols, as well as issues on privacy and security. Moreover, bioinformatics, biomedical modeling and simulation, medical imaging and visualization and, last but not least, learning and education through medical informatics systems are parts of the included topics.

A wearable healthcare monitoring unit that integrates various technologies was developed to provide patients with the option of leading a healthy and independent life without risks or confinement to medical facilities. The unit consists of various sensors integrated to a microcontroller and attached to the patient’s body, reading vital signs and transmitting these readings via a Bluetooth link to the patient’s mobile phone.

We have developed a tele-rehabilitation application for training cardiac patients. It uses a modified ergometer bicycle with a set of wireless sensors. While the patient is exercising, the ECG, blood pressure and oxygen-saturation are monitored constantly and automatically. If sensor values exceed pre-defined thresholds, the patient receives an alarm. As a result the training will either be stopped or continued at a reduced load, depending on the severity of the alarm.

Fall detection and early medical response are challenging and promising aspects of home healthcare for older adults. A two-step algorithm for falls analyzed accelerometer data for 750 test events and found significance limits for body trunk angle change as well as falls. Automated detection of falls based upon motion sensing and fuzzy logic can be based upon evidence-derived rules.
