    A textile-based wearable system, named MagIC (Maglietta Interattiva Computerizzata) has been recently developed for the unobtrusive recording of cardiorespiratory and motion signals during spontaneous behavior. The system is composed of a vest, including textile sensors for ECG and breathing frequency detection, and a portable electronic board for motion assessment, signal preprocessing and wireless data transmission to a remote computer. In this study the MagIC System has been used to monitor vital signs in cardiac inpatients and in healthy subjects during exercise and under gravitational stress. All recordings showed a correct identification of arrhythmic events and a correct estimation of RR Interval. The positive results obtained in this study support the routine use of the system in a clinical setting, experimental environments, daily life conditions and sport. View full abstract»

  • Wireless Body Sensor Network for Continuous Cuff-less Blood Pressure Monitoring

    Page(s): 11 - 15
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (6137 KB) |  | HTML iconHTML  

    This paper describes an unobtrusive IEEE 802.15.4-based wireless body sensor network (BSN) that enables continuous cuff-less blood pressure monitoring, opening up new perspectives for hypertension diagnosis and treatment, cardio-vascular event detection, and stress monitoring. We estimate the arterial blood pressure based on the pulse arrival time (PAT), which is measured with a waist electrocardiogram (ECG) and an ear photo-plethysmogram (PPG). The PAT measurement requires the synchronization of the wireless sensors' clocks. This is achieved with the flooding time synchronization protocol (FTSP). The evaluation of both the implemented time synchronization and the robustness of the wireless data transmission yielded promising results. Future work will include the study of packet collisions in synchronized IEEE 802.15.4 networks, the enhancement of the BSN with additional context-providing sensors (e.g. accelerometer, magnetometer, thermistor), and the integration of the blood pressure estimation algorithm in a wireless sensor unit.

  • A WBAN-based System for Health Monitoring at Home

    Page(s): 20 - 23
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (4663 KB) |  | HTML iconHTML  

    This paper describes a prototype system for continual health monitoring at home. The system consists of an unobtrusive wireless body area network (WBAN) and a home health server. The WBAN sensors monitor user's heart rate and locomotive activity and periodically upload time-stamped information to the home server. The home server may integrate this information into a local database for user's inspection or it may forward the information further to a medical server. The prototype may be used for ambulatory monitoring of patients undergoing cardiac rehabilitation or for monitoring of elderly at home by informal caregivers. View full abstract»

  • Design Concept of Clothing Recognizing Back Postures

    Page(s): 24 - 27
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (4610 KB) |  | HTML iconHTML  

    Continuous observation of the back enables an online feedback concerning malpositions or unhealthy movements. In this paper a design concept of clothing measuring back postures is presented. The posture detection is based on elongation measurements captured by strain sensitive fibres attached to the undershirt. The feasibility of this approach is shown by reference measurements, which provide a basis to define requirements for textile strain sensors. With these reference measurements, elongations in the range of 20% were measured on the back. The paper is completed by an overview of the state-of-the-art of potential technologies necessary for the proposed design. View full abstract»

    We describe an inexpensive in-home monitoring system designed to assist patients with traumatic brain injuries plan and execute daily activities. The system consists of fixed and wearable wireless sensors, including motion, pressure, door, flow, accelerometer, magnetometer, temperature, light and sound sensors. The sensors provide information that can be used to localize the patient, detect the activity they are engaged in and interruptions that may prevent them from completing the activity in a timely manner. During the system design and training phase, we augment the system with time stamped video and audio collection to provide a ground truth and label training data. View full abstract»

    This study was designed to assess body movement during sleep at night unobtrusively using an infrared motion detector and ZigBee communication module. In order to validate the accuracy of this system, motion records and actigraphic data were obtained simultaneously from three young healthy people for three or more consecutive nights. Significant agreement between two data was found by statistical analysis. This body movement monitoring system can assess sleep behaviors on bed without any intervention. Zigbee protocol has an advantage of low power consumption and is suitable for this application. View full abstract»

    A widespread requirement exists for a low cost and reliable health monitor in the clinical as well as home environment. The e-jacket presented here is an example of a smart clothing system with multiple bioparameter acquisition of electrocardiogram (ECG), pulse oximetry, body motion/tilt and skin temperature. The battery operated circuit has an integrated graphic liquid crystal display (LCD) screen and a 2.4 GHz wireless link. An RS232 interface provides a plug-in port for easy accessibility to remote telemedicine applications. The system incorporates an efficient ARM7 microcontroller to coordinate a list of software tasks with associated time stamp. Comfort analysis and reliability aspects have been carefully studied along with intelligent power conservation schemes. A low cost and reliable tele-medical network is proposed using an innovative e-textile solution. View full abstract»

    Sensor technology has been developed for measuring daily activity. Measurement instruments of all kinds have continued to become much smaller, consume less power, and increase in resolution and/or sensitivity. This study proposed a way to detect sleeping postures from data acquired using a tri-axis accelerometer strapped to subject's chest. We defined sleeping postures as five states focusing on basal-surface, which indicates the place of human's body on the ground. An evaluation was performed both manually by a technician and automatically by designed software. Results is that the accelerometer allowed us to accurately classify postures. Changes in posture were detected with a mean error of less than 3 s, which is acceptable for clinical cardiovascular applications. View full abstract»

  • The Challenge of Motion Artifact Suppression in Wearable Monitoring Solutions

    Page(s): 49 - 52

    Motion artifact is a major limitation in most practical implementations of wearable health monitoring devices. Especially in applications requiring continuous monitoring and high specificity, motion artifact can render a solution infeasible in real world use cases. We believe that the single most important technical challenge that will decide the success of wearable biomedical sensor systems is signal integrity. Principle possibilities to reduce artifact are explained, and some historical and modern examples are given, showing the relevance of this subject. However, still no proper models for artifact exist, nor is there a generalized approach to deal with this problem. This paper intends to call to attention the need for a common understanding in the community for a method of addressing this area objectively, and proposes next steps toward this goal.

    Health prognosis based on pulsatile blood flow signals owns a long tradition in oriental medicine. The secrets of pulse diagnosis have been partially explained by anatomy and hemodynamic analysis in contemporary western medicine. Now it is possible to obtain pulsatile blood flow signals by means of various mechanical, photoelectrical, and acoustic transducers. Meanwhile, with the introduction of advanced signal processing methods, pulsatile blood flow signals have exhibited great potentials to reveal intrinsic pathophysiological condition of cardiovascular system. Therefore, sphygmogram analyzers based on pulse signal monitoring and analysis have been proposed for health prognosis of cardiovascular system in home health monitoring. This paper is aimed to review methods and systems for pulse signal monitoring and analysis in a tutorial manner. View full abstract»
