Abstract Our work is often focused on addressing life-threatening gaps in communication and knowledge sharing — at the local level our projects have ranged from implementing an appointment reminder system for HIV/AIDS patients in Cambodia to supporting maternal child health workers in Mexico in text-messaging life-saving information to their patients. At the policy level, we [...]

A Survey on Wearable Sensor-Based Systems for Health Monitoring and Prognosis

Abstract The design and development of wearable biosensor systems for health monitoring has garnered lots of attention in the scientific community and the industry during the last years. Mainly motivated by increasing healthcare costs and propelled by recent technological advances in miniature biosensing devices, smart textiles, microelectronics, and wireless communications, the continuous advance of wearable [...]

Fast matching of sensor data with manual observations

Abstract In systems and trials concerning wearable sensors and devices used for medical data collection, the validation of sensor data with respect to manual observations is very important. However, this is often problematic because of feigned behavior, errors in manual recording (misclassification), gaps in recording (missing readings), missed observations and timing mismatch between manual observations and [...]

WearIT@work: Toward Real-World Industrial Wearable Computing

Abstract …wearable computers are often cited as an enabling technology for out-of-office applications. In fact, there has been a considerable amount of work on industrial applications of wearables. However, with the notable exception of the Symbol arim-worn system, this research has had little impact on industrial practice… Comments This article gives a general overview of [...]

Breathing Feedback Systems with Wearable Textile Sensors

Abstract Breathing exercises form an essential part of the treatment for respiratory illnesses such as cystic fibrosis. Ideally these exercises should be performed on a daily basis. This paper presents an interactive system using a wearable textile sensor to monitor breathing patterns. A graphical user interface provides visual real-time feedback to patients. The aim of [...]

Biosensors for pharmaceuticals based on novel technology

Abstract The availability of pharmaceuticals to treat and to prevent disease has brought great benefit. Nevertheless, attention is being drawn to the uncontrolled use and careless disposal of medications for humans and animals. These compounds and their metabolites are found in the environment and foodstuffs, with possible adverse risks to human health. Detection of pharmaceuticals [...]

Current approaches to trace analysis of pharmaceuticals and personal care products in the environment

Abstract A large number of xenobiotics including pharmaceuticals and personal care products are continuously released into the environment. Effluents from sewage treatment plants are well known to be the major source for introduction of pharmaceuticals and personal care products into the aquatic system. In recent years, reliable methods have been established for residue analysis of [...]

Characteristics of a multisensor system for non invasive glucose monitoring with external validation and prospective evaluation

Abstract The Multisensor Glucose Monitoring System (MGMS) features non invasive sensors for dielectric characterisation of the skin and underlying tissue in a wide frequency range…as well as optical characterisation. In this paper we describe the results of using an MGMS in a miniaturised housing with fully integrated sensors and battery. Six patients with Type I [...]

Mobile Heart Health: Project Highlight

Abstract To address psychosocial risks of cardiovascular disease, we integrated on-the-body sensors with mobile therapies for “just-in-time” stress management. Breathing visualizations and cognitive reappraisal cues appeared on the cell phone when a wireless ECG detected deviations from an individual’s baseline heart rate variability. Reactions from participants validated this concept and highlighted the need for a [...]

Detection of microorganisms using biosensors–A smarter way towards detection techniques

Abstract Along with useful microorganisms, there are some that cause potential damage to the animals and plants. Detection and identification of these harmful organisms in a cost and time effective way is a challenge for the researchers. The future of detection methods for microorganisms shall be guided by biosensor, which has already contributed enormously in [...]

Ubiquitous Health Monitoring at Home – Sensing of Human Biosignals on Flooring, on Tatami Mat, in the Bathtub, and in the Lavatory

Abstract In the graying society, it is important to monitor health-related biosignal with sensors in the living environment..In order to use biosignal data monitoring systems daily at home, noninvasive monitoring and system maintenance are crucial. We propose a method of estimating the sleep stages of sleeping subjects through noninvasive measurement of heartbeat and respiration using [...]

BEAT: Bio-Environmental Android Tracking

Abstract We introduce BEAT (Bio-Environmental Android Tracking), which provides methods for collecting, processing, and archiving one’s daily vital and spatiotemporal statistics using off-the-shelf wireless devices and biologic and environmental sensors. BEAT can operate in a self-contained manner on a mobile device and analyze vital information in real time. It uses statistics such as heartbeat variance [...]

Grid-Enabled Biosensor Networks for Pervasive Healthcare

Abstract Current advances in biosensor technology allow multiple miniaturized or textile sensors to record continuously biosignals, such as blood pressure or heart rate, and transmit the information of interest to clinical sites. New applications are emerging, based on such systems, towards pervasive healthcare. This paper describes an architecture enabling biosensors, forming a Body Area Network [...]

BIOTEX—Biosensing Textiles for Personalised Healthcare Management

Abstract …BIOTEX was an EU-funded project that aimed to develop textile sensors to measure physiological parameters and the chemical composition of body fluids, with a particular interest in sweat. A wearable sensing system has been developed that integrates a textile-based fluid handling system for sample collection and transport with a number of sensors including sodium, [...]

Quantitative Literacy on the Web of Science, 2 – Mining the Health Numeracy Literature for Assessment Items

Abstract A topic search of the Web of Science (WoS) database using the term “numeracy” produced a bibliography of 293 articles, reviews and editorial commentaries (Oct 2008). The citation graph of the bibliography clearly identifies five benchmark papers (1995-2001), four of which developed numeracy assessment instruments. Starting with the 80 papers that cite these benchmarks, [...]
