We present HealthGear, a real-time wearable system for monitoring, visualizing and analyzing physiological signals. HealthGear consists of a set of noninvasive physiological sensors wirelessly connected via Bluetooth to a cell phone which stores, transmits and analyzes the physiological data, and presents it to the user in an intelligible way. In this paper, we focus on an implementation of HealthGear using a blood oximeter to monitor the user's blood oxygen level and pulse while sleeping. We also describe two different algorithms for automatically detecting sleep apnea events, and illustrate the performance of the overall system in a sleep study with 20 volunteers

Electrochemical monitoring of neurotransmitter signaling molecules, i.e. neurotransmitters, has been often used for various biological investigations involving physiological or pathological states. In this work, we introduce alternatives to conventional electrochemical bio-monitoring and study three important neurotransmitters, dopamine, serotonin and noradrenalin, in vitro using an electrochemical technique, AC voltammetry, in combination with the Hilbert transform. We show how this method overcomes the two major difficulties of electrochemical bio-sensing: capacitance influence and the inherently nonlinear behavior of electron-transfer. We illustrate how such novel methods enhance the quantity and the quality of the biological information extracted from electrochemical measurements. This study has not only implications in general biological monitoring methodologies but also in software and hardware design and micro-fabrication

Health monitoring applications often require that the patient maintain a diary of activities so that the physiological data can be correlated to what the user was doing. However, patients are notoriously bad at self-reporting. Consequently, it would be beneficial to automatically generate an activity diary. This paper presents a proof-of-concept prototype electronic textile system for recording both physiological data and context information. It also presents some of the issues that arise in the design and use of a health monitoring and activity annotation system

A T-shirt has been developed that measures an EKG signal. This work is different to other research in the field as it focuses more on advanced interconnection and integration technologies for electronics in textiles rather than on the EKG shirt as functionality. It is the first application using an interconnection technology based on embroidery of conductive yarn that has been developed recently and published in T. Linz et al. (2005)

Summary form only given. This talk describes the efforts at MIT and the Massachusetts Eye and Ear Infirmary over the past 15 years to develop a chronically implantable retinal prosthesis. The goal is to restore some useful level of vision to patients suffering from outer retinal diseases, primarily retinitis pigmentosa and macular degeneration. We initially planned to build an intraocular implant, wirelessly supplied with signal and power, to stimulate the surviving cells of the retina. In this design electrical stimulation is applied through an epiretinal microelectrode array attached to the inner (front) surface of the retina. We have carried out a series of six acute surgical trials on human volunteers (five of whom were blind with retinitis pigmentosa and one with normal vision and cancer of the orbit) to assess electrical thresholds and the perceptions resulting from epiretinal retinal stimulation. The reported perceptions often corresponded poorly to the spatial pattern of the stimulated electrodes. In particular, no patient correctly recognized a letter. We hope that chronically implanted patients will adapt over time to better interpret the abnormal stimuli supplied by such a prosthesis. Experiences with both animals and humans exposed surgical, biocompatibility, thermal and packaging difficulties with this epiretinal approach. Two years ago we altered our approach to a subretinal design which will, we believe, reduce these difficulties. Our current design places essentially the entire bulk of the implant on the temporal outer wall of the eye, with only a tiny sliver of the 10 micron thick microelectrode array inserted through a scleral flap beneath the retina. In this design the entire implant lies in a sterile area behind the conjunctiva. We plan to have a wireless prototype version of this design ready for chronic animal implantation this Spring

Cardiovascular diseases (CVD) are the leading source of death in the western world and in particular, in Europe CVD cause 45% of all deaths. Besides, heart failure (HF), the paradigm of CVD, affects mainly people older than 65. Facing this reality, the European Union funded MyHeart Project, whose mission is empowering citizens to fight CVD by means of a preventive lifestyle and an early diagnosis. This paper presents an innovative integrated solution for the assessment of heart failure: HF management (HFM). HFM is a heart failure disease management system that makes use of innovative approaches, based on information technologies (IT) and wearable technologies, for the continuous assessment of HF progression and cardiovascular risk stratification. By integrating patient data from different sources with special emphasis in the information obtained from extensive ECG processing the system assesses the patient's cardiac condition. Rather than just merely evaluating the cardiovascular status, HFM is designed to motivate patients to acquire an active role in their health management and to help them to improve their cardiac condition by promoting physical exercise

In order for new and emerging physiologic sensors to play increasingly larger roles in the monitoring and management of ill and injured patients, the information they generate must be standardized in an XML format so that it can be integrated with the developing patient care record. To satisfy this need, we have built a prototype sensor gateway that communicates sensor data via HL7v3 messaging using SOAP transport and XML encoded data. We have connected the sensor gateway to a working sensor network called CodeBlue

Wearable monitoring networks are designed to augment and improve daily life. These systems require sensors and various electrical components to be mounted on the body. We propose a technique of using a DC powerline-carrier communication system to integrate the system components. This simplifies the wiring and the routing of connectors, and reduces the system weight and bulk. We use conductive fabrics as the transmission medium of the system. A method of predicting the DC behavior of such a garment is presented, and its utility in the design of such garments is discussed
