This paper presents the design, implementation and test of a watch with the capability to measure multiple physiological signals, such as photoplethysmography (PPG), electrocardiography (ECG), and some physiological parameters extracted from PPG and ECG. Based on the PPG and ECG signals, the pulse rate and heart rate could be extracted respectively. Moreover, the pulse transmit time (PTT) could be...
The system which monitors the various physiological signal plays a vital role in diagnosing the diseases of a patient in time. Wireless transmission of Electrocardiogram (ECG) signal enables the mobility of the patient and doctor. The device captures and provides the ECG data across networks which can be continuously monitored through any display device in real-time. The proposed wearable device contains...
Diabetes mellitus is a chronic disease and its prolonged existence may cause proliferation of diverse abnormalities in human physiological system. Maintaining a healthy lifestyle can improve the condition of a diabetic patient. However, continuous monitoring of diabetes level is necessary for adapting diets and others for healthy life, which requires clinical settings or medical consultation. Thus,...
In this paper we report a design and fabrication process for a screen printed, skin-mounted hybrid system for electrocardiogram (ECG) measurements. The system consists of printed electrodes on a stretchable bandage substrate designed to be attached to the chest, an electronics module, and a data receiving device. The electronics unit is reversibly attached to the single-use electrode bandage to measure...
We report a low cost mobile EEG system for characterizing cortical auditory responses. The system is built using commercial off-the-shelf components and each unit costs less than $200. It measures seven EEG channels plus one audio channel (envelope only), and communicates the data to external devices via Bluetooth. A novel implementation was pursued in order to support local signal compression using...
In this paper, we present a stretchable wearable system capable of i) measuring multiple physiological parameters and ii) transmitting data via radio frequency to a smart phone. The electrical architecture consists of ultra thin sensors (< 20 цm thick) and a conformal network of associated active and passive electronics in a mesh-like geometry that can mechanically couple with the curvilinear surfaces...
A high density wireless electroencephalographic (EEG) platform has been designed. It is able to record up to 64 EEG channels with electrode to tissue impedance (ETI) monitoring. The analog front-end is based on two kinds of low power ASICs implementing the active electrodes and the amplifier. A power efficient compression algorithm enables the use of continuous wireless transmission of data through...
This paper describes, the design and implementation of a wearable remote ECG monitoring system, which comprises of the wearable ECG device and the mobile phone application to communicate with the ECG device. The wearable device captures the real time ECG of the person wearing the device and communicates with a remote server using the person's own mobile phone. The device captures ECG using three electrodes...
With the increasing requirements of mobile ECG monitoring, a convenient mobile ECG monitoring system solution is proposed in this paper. The monitoring terminal is designed by using MSP430 to achieve ECG signal acquisition, amplification and A/D conversion. CC2540 integrating low-power Bluetooth 4.0 BLE-Stack is also used. System has the function of mobile ECG data transmission from the monitoring...
This paper reports the development of a wireless, wearable, multi-sensor suite and its integration as part of a smart garment for point-of-care diagnosis of cardiorespiratory disorders with a particular focus on sleep apnea screening. The suite is designed to synchronously gather 3-lead vectorcardiogram signals sampled at 250 Hz from a custom-designed hardware, heart sound signals gathered at 250...
A wearable, telemetric, biosignal monitoring device (so-called body sensor) for long-term, continuous healthcare monitoring is presented in this paper. The body sensor is worn across the chest of patient by using a commercial available Polar strap, for recording beat-to-beat heart pulsation. The body sensor is connected to a smart phone through Bluetooth channel. The smart phone is used to compensate...
According to WHO(World Health Organization), estimated about 17 million people die around the world due to cardio vascular diseases, particularly heart attack, in them most of the deaths are due to untimely intervention. If proper medical care can be given to the patients at the right time their lives can be saved, for that all we need is a system that continuously monitors ones ECG signal, so we...
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...
Capacitive EGC sensors are a promising approach for future ECG measurement systems as they do not rely on a moist and direct skin contact. This is especially desirable for long-term monitoring, because capacitively coupled electrodes (CCE) do not cause skin irritations to the patient. In this paper, we present a textile integrated CCE-based ECG monitoring system for long-term application. The system...
We developed and tested the Berkeley Tricorder, a health monitoring device capable of measuring a subject's ECG, EMG, Blood Oxygenation, Respiration (via Bioimpedance), and motion--almost equivalent to the feature set of a hospital bedside patient monitor. Our focus has been a highly integrated design incorporating the radio and all associated circuitry on a single PCB. The device stores data locally...
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...
