Human motion and posture detection based on the multi-nodes sensors will help people to realize the law of body's movement through obtaining the kinetic parameters, so that it can be used as a quantitative analysis tool for some specific applications such as health care, sport training and military affairs, etc. Compared with optical method, inertial sensors for body motion analysis have advantages...
This paper provides a review of technology that has emerged to facilitate pervasive brain-computer interface applications. Such technology is beginning to be applied to the human-computer interface, as part of multimodal interaction. As the technology taps into brain state and provides an associated quantitative assessment, it has potential for the real-time assessment of a person's cognitive state...
This paper describes a novel method and system to monitor and compute swimmer performance. We placed a 3-axes accelerometer onto the athlete's back. This accelerometer allows for detecting and interpret single gestures during the training session. The acquired data can be processed to compute synthetic parameters for a qualitative assessment of the performance. Symmetry and no. of foot-/arm-stroke...
The increasing size of the elderly population is driving the development of ambient assisted living systems and telehealth. The recognition of the user's everyday activities and detection of alarming situations are important components of such systems. Moreover, the monitoring of vital signs, like the ECG, has a key role in telecare and telemonitoring systems. Therefore, in this paper we propose a...
This paper discusses the reliability of textile sensors in wearable monitoring application. A methodology for the validation of new textile electrodes for monitoring subjects in daily activities is proposed. The protocol is divided in 2 phases: a laboratory set of tests to verify the “absolute” reliability of the electrodes; a second set of trials is carried out with subject performing activities...
Wearable sensors in Wireless Body Area Networks (WBANs) provide health and physical activity monitoring. Modern communication systems have extended this monitoring remotely. In this survey, various types of wearable sensors discussed, their medical applications like ECG, EEG, blood pressure, detection of blood glucose level, pulse rate, respiration rate and non medical applications like daily exercise...
Patients are not able to call for help during a generalized tonic–clonic epileptic seizure. Our objective was to develop a robust generic algorithm for automatic detection of tonic–clonic seizures, based on surface electromyography (sEMG) signals suitable for a portable device. Twenty-two seizures were analyzed from 11 consecutive patients. Our method is based on a high-pass filtering with a cutoff...
Connected health represents an increasingly important model for health-care delivery. The concept is heavily reliant on technology and in particular remote physiological monitoring. One of the principal challenges is the maintenance of high quality data streams which must be collected with minimally intrusive, inexpensive sensor systems operating in difficult conditions. Ambulatory monitoring represents...
Current methods for assessing the efficacy of treatments for Parkinson's disease (PD) rely on physician rated scores. These methods pose three major shortcomings: 1) the subjectivity of the assessments, 2) the lack of precision on the rating scale (6 discrete levels), and 3) the inability to assess symptoms except under very specific conditions and/or for very specific tasks. To address these shortcomings,...
With the tremendous advancements in low cost, power efficient hardware and the recent interest in biomedical embedded systems, numerous traditional biomedical systems can be replaced with smaller embedded systems that do real-time analysis to provide bio-feedback to the users. This paper presents a prototype of an embedded system which is capable of real-time data collection, using analog and digital...
An ECG monitoring system comprised of six wearable textile-based electrodes is used to detect the ECG and sitting posture of vehicle drivers. The electrodes are washable, comfortable, sewed into ordinary shirt, and not connected with extra wires; as a result, they not only detect drivers' ECG while they move, but also prevent hindering their driving. While drivers change the sitting postures, different...
The study of mechanomyographic (MMG) signals of respiratory muscles is a promising technique in order to evaluate the respiratory muscular effort. In this work MMG signals from left and right hemidiaphragm (MMGl and MMGr, respectively) acquired during a respiratory protocol have been analyzed. The acquisition of both MMG signals was carried out by means of two capacitive accelerometers placed on both...
This study demonstrates a novel monolithic TPMS (tire pressure monitoring systems) using CMOS MEMS processes. This TPMS monolithic integrates the 3-axis capacitive accelerometer, capacitive pressure sensor, and platinum (Pt) thermal-resist temperature sensor on a single chip. The TPMS has been successfully implemented using TSMC 2P4M process and our in-house post-process. The footprint of TPMS chip...
Monitoring patients continuously while they go about their daily activities is a challenging goal. It requires long-term recording of cardiovascular and other electrophysiological signals and contextual information such as body motion. Here we present a small, battery powered, user customisable, portable monitor capable of recording three-axial acceleration, skin temperature, and up to four bio-signals...
