The goal of this research is to develop a wearable electrocardiogram (ECG) apparatus with Bluetooth 4.0 function which can detect the heart beats, mental index and physical activity in real time. It measured one lead ECG signal. Its specification follows the standard of International Electrotechnical Commission (IEC) for medical electrical equipment and ambulatory electrocardiographic systems (Holter...
In this paper a highly flexible platform for biomedical data acquisition and processing is presented. The modular design of its hardware enables it to cover a wide range of applications: from a single-lead electrocardiography (ECG) heart-beat monitor, to a sleep laboratory setup including multi-channel electroencephalography (EEG), electro-oculography (EOG), pulse oximetry, sleep position monitoring...
We address the critical issues raised in mobile healthcare monitoring and propose a new solution to resolve respective problem. This paper presents self-developed BCG monitoring, posture correction system and respective application. A 3-loadcell chair-type BCG system which allows continuous heart status monitoring and posture correction at the office and daily life is designed and developed. The implemented...
Technology advancements of sensors, low power mixed-signal/RF circuits, and Wireless Sensor Networks (WSNs) made it possible to construct compact and low cost solutions for a wide range of applications such as healthcare, surveillance, building monitoring, sports and fitness, etc. A new emerging generation of WSN is the Body Sensor Network which is suitable to monitor of the human body, mainly for...
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...
Various ECG instruments have addressed a wide variety of clinical and technical issues. However, there is still scope for improvement in them particularly in the area of their susceptibility to noise, lack of universal connectivity and off-line processing. In emergency situations, real-time health parameter is crucial. According to the American Heart Association [1], treatment of a patient experiencing...
Available conventional methods of cardiac patient monitoring mostly perform offline analysis and restrict the mobility of the patients within a hospital or room. Even if an analysis is made, the results are recorded only on a server, where the doctor has to go and make the analysis and then initiate a treatment. This is patently time consuming. Hence, this work proposes a portable telemedicine system...
Portable sleep monitoring has an increasing demand due to the increasing amount of sleep disorder patients. The HRV and sleep posture changed with different sleep stages. This paper therefore proposed a portable sleep monitoring system based on ECG and accelerator signals. This system contained single ECG sensor and a tri-axis accelerator sensor, with microcontroller MSP430 for low power analog-to-digital...
Electromyogram (EMG) is used in various circumstances such as diagnostic and prosthesis control. This paper deals with the diaphragmatic electromyogram (EMGdi) as a controller of mechanical ventilation. However, recorded EMGdi signals are always contaminated by electrocardiogram (ECG). Cancellation of the ECG contamination, especially in real-time, is not a simple operation because the spectra of...
Most current wireless biomedical signal transceivers use range-limiting communication. This work presents a low-cost biomedical signal transceiver that uses Bluetooth wireless technology. The design is implemented in a modular form to be adaptable to different types of biomedical signals. The signal front end obtains and processes incoming signals, which are then transmitted via a microcontroller...
Within this study, three different Bluetooth/spl trade/ sensor systems, replacing cables for transmission of biomedical sensor data, have been designed and evaluated. The three sensor architectures are built on 1-, 2- and 3-chip solutions and depending on the monitoring situation and signal character, different solutions are optimal. Essential parameters for all systems have been low physical weight...
