Common hospital monitoring set up includes nurses taking rounds throughout their assigned wards and checking the patient's vital signs. This process is very time consuming and prone to human errors, especially for large scale hospitals. As a solution, an Internet of Things (IoT) based pulmonary monitoring system was proposed. The system uses a single-lead heart rate sensor connected to a microcontroller...
Current mobile revolution is leading to an increase of wearable health devices development and consequently a growth in ambulatory monitoring area. These systems can be applied in ambulatory diseases management and diagnosis, personal health monitoring or sports performance enhancement, providing physiological and body-area ambiance data during daily normal activities. Nowadays several devices in...
A novel wearable sensor system for seizure monitoring of neonates comprised of smart clothing, video recording and cloud platform is presented. Textile electrodes and Inertial Measurement Unit (IMU) are embedded in the smart clothing to obtain ECG signal and motion signal whereby epileptic seizure detection algorithm is performed. Moreover, a video monitoring module provides real-time information...
Frequent monitoring is required for chronically ill cardiac patients to ensure superior treatment. This paper presents a low-cost, novel wearable electrocardiogram (ECG) measuring unit for consistent use. In this study, the ECG signal is accumulated by a three electrode data acquisition system and measured by an integrated signal conditioning block AD8232. The analog signal from AD8232 is converted...
A simple heart rate (HR) monitoring system designed and developed using the Giant Magneto-Resistance (GMR) sensor is presented in this paper. The GMR sensor is placed on the wrist of the human and it provides the magneto-plethysmographic signal. This signal is processed by the simple analog and digital instrumentation stages to render the heart rate indication. A prototype of the system has been built...
Following a surgical procedure, patients are monitored in an ICU until physically stable, after which are discharged to a ward for further evaluation and recovery. Usually, ward evaluation does not imply continuous physiological parameters monitoring and therefore patient relapse is not uncommon. The present paper describes the steps taken to design and build a low-cost modular monitoring system prototype...
This report describes a small heartbeat monitoring system using capacitively coupled ECG sensors. Capacitively coupled sensors using an insulated electrode have been proposed to obtain ECG signals without pasting electrodes directly onto the skin. Although the sensors have better usability than conventional ECG sensors, it is difficult to remove noise contamination. Power-line noise can be a severe...
This paperwork describes the development and test of circuitry and software to enable the use of Android mobile phones equipped with Bluetooth to receive the incoming electrocardiogram (ECG) signal from a user and show it in real-time on the cell phone screen. The system comprises three distinct subsystems. The first one is dedicated to condition the analog ECG signal, preparing it for conversion...
A novel idea of applying a proposed radio frequency transducer architecture for wireless monitoring of sleep apnoea patients has been presented in this article. The architecture has been realized on a primary prototype and tested from baseband to 2.5 GHz band. The experimental results prove that this architecture can be used for wireless sleep apnoea monitoring for the design of each portable transducer...
Fetal heart rate monitoring is fundamental to infer information about fetal health state during pregnancy. The cardiotocography (CTG) is the most common antepartum monitoring technique. Abdominal ECG recording represents the most valuable alternative to cardiotocography, as it allows passive, non invasive and long term fetal monitoring. Unluckily fetal ECG has low SNR and needs to be extracted from...
In this paper, we present the application of wireless sensor technology and the advantages it will inherently have for neonatal care and monitoring at Neonatal Intensive Care Units (NICU). An electrocardiography (ECG) readout board and a wireless transceiver module developed by IMEC at the Holst Centre in the Netherlands are embedded in the proposed wireless sensor systems in combination with the...
We present a prototype of an integrated blood pressure (BP) and electrocardiogram (ECG) device for multi-parameter physiologic monitoring. A standard BP pressure cuff and an ordinary wristband have been modified to incorporate in them dry ECG electrodes made of thin conductive fabric. The modified BP cuff and wristband are coupled with commercially available hardware and software to harvest simultaneous...
The HeartCycle EU research project aims to provide disease management solutions for cardiac patients. Developed within HeartCycle, IMAGE is a wearable device capable of acquiring ECG, bioimpedance, and acceleration measurements. The acquired signals are stored in onboard memory and processed, while the results are wirelessly transmitted in real time to a base station. Base station processed data is...
An evaluation of motion artefact for a newly CE approved wireless bodyworn monitoring device is presented. This evaluation has shown that the system under test has greatly reduced motion artefact with comparison to an FDA-approved leaded system. Analysis of physiological data, such as quality of ECG signal, accuracy of recording of heart rate, temperature and ECG R-R interval has shown the system...
This paper presents the development of a guided project course that aims to help biomedical engineering students integrate technical concepts in electric circuits, biomedical instrumentation, and human physiology. Our course involves the design of an electrocardiogram monitor from scratch, and it differs from other lab-based courses that comprise a series of individual experiments. There are three...
Pervasive healthcare technology is one of the methods for meeting the challenges of an aging population in many western world countries, as well as an expected major shortage of healthcare personnel. The OpenCare Project is an open source infrastructure framework, designed to be used by researchers and corporate developers for developing experimental assistive living prototypes. The Personal Communication...
