Analysis of autonomic nervous system activity is a subject increasing interest in the fields health care and handicap management, as it provides information on emotional, sensorial, cognitive states patient. In this context, simultaneous measurement several physiological signals using small, discreet, mobile devices required, order to unobtrusively obtain such under real-life conditions. We have therefore developed an ambulatory device which enables heart rate, electrodermal activity, skin...

Improvement of the quality and efficiency health in medicine, at home hospital becomes more important Designed to be user-friendly, smart clothes gloves fit well for such a citizen use monitoring. Analysis autonomic nervous system using non-invasive sensors provides information emotional, sensorial, cognitive physiological analysis. MARSIAN (modular autonomous recorder measurement system) is wrist ambulatory monitoring recording with glove detection activity system. It composed "smart tee...

As the thermoregulation centres are deep in brain, cerebral temperature is one of most important markers fever, circadian rhythms physical and mental activities. However due to a lack accessibility, brain not easily measured. The axillary, buccal, tympanic rectal temperatures do reflect exactly temperature. Nevertheless used as probably reliable indicator core body can be measured using NMR spectroscopy, microwave radiometry, near infrared ultra-sound thermometry. none those methods amenable...

Given the soaring costs associated with treatment of ever more prevalent chronic disease, it is widely agreed that a revolution required in health care provision. It often thought necessary technology already exists for home-based monitoring such patients and other factors which are holding back widespread clinical uptake these new tools. The authors suggest sensor-related technologies not as advanced may first appear; certainly they generally adequate robust, long-term under real-life...

Health smart clothes are in contact with almost all the surface of skin offer large possibilities for location sensors non invasive measurements. Head band, collar, tee-shirt, socks, shoes, belts chest, arm, wrist, legs ... provide localization specific purpose taking into account their proximity an organ or a source biosignal, and also its ergonomic possibility (user friendly) to fix sensor, associated instrumentations (batteries, amplifiers, signal processing, telecom, alarm, display ...)....

Skin temperature is a relevant and effective indicator for objective evaluation of human sensations thermal states according to the surrounding stresses. Managed by skin blood flow, sympathetic nervous system (constriction sweating), subcutaneous structure facial vein patterns, coetaneous variability can give information non-invasively on many physiological functions. These informations are deduced from images obtained far infrared imaging (7 - 14 mum). The work presented here deals with...

Improvement in quality and efficiency of health medicine, at home hospital, has become paramount importance. The solution this problem would require the continuous monitoring several key patient parameters, including assessment autonomic nervous system (ANS) activity using non-invasive sensors, providing information for emotional, sensorial, cognitive physiological analysis patient. Recent advances embedded systems, microelectronics, sensors wireless networking enable design wearable systems...

Objective To study of the microcirculatory effects elastic compression stockings. Materials and methods In phlebology, laser Doppler techniques (flux or imaging) are widely used to investigate cutaneous microcirculation. It is a method explore microcirculation by detecting blood flow in skin capillaries. Flux imaging instruments evaluate, non-invasively real-time, perfusion micro vessels. Such tools, well known vascular community, not really suitable our protocol which requires evaluation...

Objective: The aim of this paper is to report quantitative and qualitative characteristics bruxism events recorded in sleeping humans with a new smart ambulatory system specifically designed measure dental clenching grinding forces. device wireless rechargeable, which enables its use over extended periods.Methods: Thirty recordings were obtained from volunteer subjects who wore the at home during 10 consecutive nights (Clinicaltrials.gov N° NCT03363204).Results: showed that was able...

This paper presents a novel method to prepare stretchable conductors and pressure sensors based on the gold/polydimethylsiloxane (PDMS) system. The gold films were sputtered onto structured PDMS surfaces produced with photolithographic surface treatment aim of reducing tensile strains in film. Scanning electron microscopy (SEM) atomic force analyses showed that these 3D patterns reduce cracks delaminations Electrical measurements indicate also protect against repeated cycling, although...

Pressure ulcers are a serious health problem for people with mobility disorders, like elders in acute care, long-term and home care settings. It also concerns paraplegics, tetraplegics or persons burned injuries. result significant morbidity mortality. Consequences high human suffering, cost terms of treatment. Several risk factors have been identified the development pressure ulcers: they classified into extrinsic intrinsic factors. Extrinsic include interface pressure, shear forces,...

The purpose of MAPI project is to propose a method for interface pressure measurement. This must be exact, easy build, low cost, and take into consideration viscoelastic characteristics the skin human morphology. main areas related ergonomics seating surfaces prevention ulcers. An additional stage was performed by developing an electro-pneumatic sensor directly integrated seat. use presents acceptable characteristics. average error 2.58%, standard deviation 1.66 mmHg.
