Freeform (physically flexible, stretchable and reconfigurable) electronics can be critical enabler for advanced personalized healthcare. With increased global population and extended average lifetime of mankind, it is more important than ever to integrate advanced electronics into our daily life for advanced personalized healthcare. In this paper, we discuss some critical criteria to design such electronics...
In this study, a bed-leaving detection system using piezoelectric sensors was proposed to monitor vital signs of the human body such as arterial blood pressure, breathing motion, and body movement. This study reports on the details of a fast and concise algorithm designed to detect vital signs from vibration signals that are recorded via piezoelectric sensors installed inside a pillow and under a...
Tongue fur is an important objective basis for clinical diagnosis and treatment in western medicine and tongue diagnosis for Chinese medicine. Given the high penetration and built-in sensors of smartphones, and the need for continuous monitoring of health conditions, we propose an automatic tongue diagnosis framework on smartphone. However, tongue images taken by smartphone are quite different in...
Human Activity Recognition (HAR) is a powerful tool for understanding human behaviour. Pervasive sensors, such as wearable devices, have an increasing market penetration and generate a tremendous amount of data. The myriad of available clinical and consumer-grade wearables generate a continuous time series of a person's daily physical exertion and rest. Applying HAR to the activity time series can...
Real-time monitoring of physiological data can reduce the likelihood of injury in noncombat military personnel and first-responders. MIT Lincoln Laboratory is developing a tactical Real-Time Physiological Status Monitoring (RT-PSM) system architecture and reference implementation named OBAN (Open Body Area Network), the purpose of which is to provide an open, government-owned framework for integrating...
Wearable sensors for heart-rate, ECG, blood pressure, and blood glucose are gaining increasing prominence in home-based healthcare. Though the medical sensory data is now routinely encrypted and signed, the timestamp associated with the data, which is needed for accurate correlation and reconstruction of medical events, remains poorly secured. In this paper we first motivate the problem by demonstrating...
Respiratory Rate (RR) is one of the key vital signs that is routinely monitored by medical professionals and health care providers. Remote monitoring of it helps in detecting several clinical conditions and low-cost sensors are needed in telemedicine. Most of the current day measurement systems for RR involve the use of sensors that are in contact with the subject, causing discomfort. In case of neonates,...
With diabetes patients doubling every year especially in the UAE there is a need to curb this epidemic and help those who are affected to live an active life. Continuous monitoring of health indicators ensures prompt medical attention and reduction in fatalities. The primary challenge to continuously monitor diabetes is that glucose level measurement requires invasive methods. Moreover, continuous...
Cardiac arrhythmia detection and classification is of outmost importance for early diagnosis to reduce significantly the rates of morbidity and mortality of patients with heart disease. In particular for patients with silent cardiac symptomatology, the advances in wearable sensing technology offer a promising solution for on-line, real-time detection of intermittent tachyarrhythmia events that otherwise...
A wearable system based on a breathable cloth wristband equipped with stretchable strain gauge sensors were assembled and tested to detect a set of 16 different hand gestures. The sensors embedded on the wristband prototype do not require a direct contact with the skin, thus maximizing comfort. To evaluate the performance of the developed band, different gestures were labelled by using grasping information...
Sleep deprivation distracted most people. The common ways to monitor people sleeping are electroencephalogram and polysomnography. Recently, wearable devices provide function to estimate sleep status. However, in some situations people feel uncomfortable to wear devices, such as elder with dementia. This paper presents a scheme to estimate sleep status based on wearable free device. We utilized SVM...
Wearable health-monitoring systems must achieve a balance between the often opposing goals of hardware overhead and classification accuracy. Prior works have presented various approaches to dynamically scale the accuracy of these systems as a function of available resources. In this paper, we present a framework which retroactively improves the accuracy of prior estimates when resources become available,...
Blood Pressure (BP) is a crucial vital sign taken into consideration for the general assessment of patient’s condition: patients with hypertension or hypotension are advised to record their BP routinely. Particularly, hypertension is emphasized by stress, diabetic neuropathy and coronary heart diseases and could lead to stroke. Therefore, routine and long-term monitoring can enable early detection...
The emergent importance of the sleep medicine together with the rapid adoption of mobile devices and wearables along with a growing habit for using these devices on the daily-living activities offer an opportunity to use them as a sleep monitor. Traditional sleep monitoring systems, such as polysomnography, involves a myriad of sensors attached around the patients' body, and therefore is limited to...
Recent technological advances and the ever-greater developments in sensing and computing continue to provide new ways of understanding our daily mobility. Smart devices such as smartphones or smartwatches can, for instance, provide an enhanced user experience based on different sets of built-in sensors that follow every user action and identify its environment. Monitoring solutions such as these,...
This paper is a study of wearable antenna design for medical applications. A literature review of existing wearable systems is performed, with specific attention paid to the antenna element. Two antennas working at 2.4 GHz were simulated using a software tool; firstly a basic rectangular patch on FR4 substrate and the other on soft textile material. The bending performance of the soft textile antenna...
The healthcare domain is mission critical and vast research efforts keep being funded in order to improve life quality of people. Health management consists of specific cooperation intensive activities, while medical knowledge and systems are spatially and functionally distributed. Also, medical data flows are inefficient for dynamic data delivery to stakeholders while the manifold of medical care...
Consistent power and cost effective health monitoring has become the need of the hour especially for the unstable, chronically and critically ill. Here we present a novel architecture and algorithmic methodology combining the sensing subsystem, symptom summarization, and data transmission. Physiological parameters from multiple sensors feed into a severity quantizer and a subsequent multiplexer, the...
People with developmental disabilities often face difficulties in coping with daily activities and many require constant support. One of the major health issues for people with developmental disabilities is personal hygiene. Many lack the ability, poor memory or lack of attention to carry out normal daily activities like brushing teeth and washing hands. Poor personal hygiene may result in increased...
The problems faced by most senior citizens living alone at homes along with their poor health conditions have motivated the development of a home monitoring system which aims at improving their wellness and health-care. The purpose of this system is to monitor the physiological parameters in real time, together with the help from a computer vision module. Several research works on this area have been...
