Today dietary assessments require manual information sampling in paper or electronic questionnaires on food type and other diet-related details. Low accuracies of 50% are confirmed for self-reporting, which weakens diet coaching effectiveness and is a major limitation for today's diet programs. Automatic Dietary Monitoring (ADM) using ubiquitous sensors was proposed to alleviate this problem. In this...
There is a need for long term monitoring of the brain during intensive care. This is e.g. the case for newborn babies that have been exposed to hypoxia during delivery. Electroencephalography (EEG) is the technique of choice. To get a clear and detailed view of the brain activity a large number of EEG electrodes should be used. Applying traditional electrodes one by one is a time-consuming and technically...
Autonomous sensor networks that provide patient monitoring are growing in popularity due to the prospects of lower cost, and the ease of supervision by the physician. Physiological signals monitoring could result in large volume of data being either transmitted or stored which can then be directly related with the energy consumption for the system. This paper presents an EEG compression scheme that...
This paper aims to present a novel architecture for the indoors Ambient Assisted Living domain. This domain synthesizes features from the home-based e-health and ambient intelligence scientific areas. The HERA system addresses mainly the needs of elderly in the early stages of the Alzheimer disease aiming to improve the quality of their home life and extend its duration. Other user categories are...
There is usually a tradeoff between security strength and computing power in a real time health monitoring system. In this paper, we firstly investigated the performance of several cryptographic protocols for different data sizes applied on the system in different network condition, and then presented a security protocol adaption scheme allowing to automatically change the encryption algorithm to...
Patients with arrhythmias would greatly benefit from daily ECG monitoring, both for diagnosis and therapy optimization. The aim of this study was to simulate several ECG monitoring strategies which could help in optimizing a home monitoring device. Simulations were performed using data from patients implanted with DDD-CLS pacemaker for Brady-Tachy Syndrome (Burden II Study). The data analysis was...
There is a strong motivation for the implementation of electronic identification systems and wireless sensors in hospitals. This work presents a sensor enabled passive RFID tag for patient monitorization. Special attention is paid to the analog FE, which has been designed and implemented in a low cost 0.35 μm CMOS standard process. The proposed front-end architecture allows the implementation of power...
Health care provision is facing resourcing challenges which will further increase in the 21st century. Health care mediated by technology is widely seen as one important element in the struggle to maintain existing standards of care. Personal health monitoring and treatment systems with a high degree of autonomic operation will be required to support self-care. Such systems must provide many services...
In this study, our purpose is the development of measuring and monitoring system to investigate the brain activity in usual behavior without restraint. Using this system, we can obtain physiological information such as EEG, ECG and cerebral blood of the subject always and anywhere, even if subjects walk around or move freely. In this study, we applied this system to evaluate the concentration state...
Today's technological growth has made ubiquitous health care accessible to all by means of wearable health monitoring system. Such a system is essential for continuous monitoring of physiological signals and to provide early warnings for the chronic illness. The major challenge lies on the selection of processor and transmission mode. This paper highlights on the pilot study of developing ubiquitous...
Personal disease management and prevention are essential for promoting the healthy community. How to establish the health promotion environment becomes an attractive topic in nowadays. In this paper, we investigate the approaches of patient monitoring and care under the cloud-based telecare system. By considering the scenarios for fixed and mobile users, the cost-effective health promoting methods...
We propose a method for night time monitoring of heart rate. Our method uses one or more pressure sensitive elements integrated into a wristwatch. The sensing elements are made of film type electret material called EMFi (Electro Mechanical Film). We designed the signal processing algorithms keeping in mind on-line processing and later integration into a micro controller for wearable applications....
It has been reported that the abnormal concentration of acetone in exhaled air is an indicator of diabetes and the concentration rises progressively with the blood glucose level of patients. Therefore, the acetone in human breath can be used to monitor the development of diabetes. In this paper, we introduce a breath analysis system to measure acetone in human breath, and therefore to evaluate the...
The aim of this study was to investigate the effects of accelerometer placement, within the practical constraints of a smart garment, for the purposes of monitoring gross levels of activity. Experiments involved collection of data from three participants who were instructed to walk on a motorized treadmill at speeds of two, three and four miles per hour. Accelerometers were placed on a specially designed...
ITS (Intelligent Transport System), which connects people, vehicles and roads by information and communication technologies, has been drawing much attention these days. Telematic services, in particular, have been deployed by domestic as well as foreign automobile companies in various ways. However, in most cases their services are intended to support drivers themselves. In the meantime, provision...
In this paper we present the early development phases of an occupancy monitoring sensor system for an intelligent sofa and related user and service scenarios in the context of living environment for older persons. The paper presents details of the technical solution of the intelligent sofa and the test results of its laboratory use. Information integration concept with other elements in the case environment...
Japan is facing two problems of aging population and declining birth rate, which lead to a scenario that the elderly are at home alone and no one takes care of them most of time. Therefore, there is need of developing the elderly care supporting systems. This paper presents a system for supporting the elderly at home in medicine management, medicine taking monitoring, and medicine taking assistance...
Due to home accidents occurring within the world's aging population, especially with the accidental stumble and falling of the elderly, mortality and morbidity from falls have become one of the major issues in the health care system. In most developed countries, most frequent stumbles and falls occur in and around the community or at home. A number of wearable devices integrated with accelerometers...
We have proposed a network based system for long-term recording pulse rate (PR), respiration rhythm (RR), and body movement (BM) detected by a sensor unit placed beneath a pillow during sleep from pressure variations corresponding to changes in the heartbeat and respiratory motion. In this research, we studied the analysis of the long-term monitored PR, RR, and BM during sleep recorded by this system...
