This paper deals with the development of unique human health monitoring system which can collect various health parameters from the patient and transmits the data over the internet for health monitoring system. This system works in two modes namely adult patient monitoring mode and child monitoring mode.
Electrocardiography (ECG) signal is currently recorded using minimum three electrodes, two electrodes for differential measurements and the third one to increase the Common Mode Rejection Ratio (CMRR). This paper presents a method to increase the CMRR of the analog front-end of ECG circuits. It is shown that the CMRR of ECG systems can be improved significantly without the need to the third electrode...
Pulse oximeters use photoplethysmographic (PPG) signals for measurement of oxygen saturation in arterial blood. They measure volumetric changes in the blood flowing through the body, usually extremities such as a finger or an ear lobe. The peripheral pulse signal obtained by transmitted light through the illuminated body extremity, gets modulated by heart synchronous pulse, respiratory activity and...
This is an experimental study for acquisition, measurement, processing and display of human health parameters like ECG, Body temperature as well as Saline status. Primarily ECG signal is detected using surface electrodes. As the signal is very feeble in amplitude so an instrumentation amplifier is designed to amplify the acquired ECG signal. Second order Butterworth filter is used to remove the noise...
Instrumentation amplifiers (IA) used in wearable biomedical monitoring systems have to satisfy several performance requirements, such as low-voltage supply and low-power consumption, enabling increased portability. In the same time, a very important feature is wide range parameter programmability. This paper proposes a solution to implement electronic gain programming into an IA. The proposed solution...
A healthcare monitoring system is designed which can be used in the hospitals to monitor people who need to an intensive care. This system can be implemented on many biological signals. ECG signal is selected for put in practice in this work. Since ECG signal is measured in mille volt, it needs to be amplified. Also it is a noisy signal, so it needs to be filtered. ECG acquisition part contains AD620...
Some factors that have increased cardiovascular incidents are sedentary lifestyle, poor eating habits, smoking, stress; hence the importance of continuously monitor cardiac activity in people.

This study was aimed to design an electrocardiograph (ECG) system by the 0.35 μm CMOS technology. In this study, a two-stage operational amplifier was taken as the building block for the design of instrumentation amplifier and filters. In our measurement, excellent performance was verified by the fabricated chips.
The efficient ECG data acquisition and transmission is important for detecting the heart disorders. This paper shows a platform of an ECG module, capable of monitoring ECG signals via ARM9 web-server technology in remote PC. In the current version, Ethernet is used for communication between server and PC, to illustrate the working of the module. It is showed in two fronts: 1) The device would get...
Heart Rate (HR) and Respiration Rate (RR) are considered among the most useful biomedical signals to be observed from a subject in order to evaluate his/her health conditions. HR and RR are routinely monitored in patients recovered in hospitals and eventual variations of these quantities need to be measured and reported. Today HR and RR are measured with standard methods: electrocardiography (ECG)...
The proposed non-contact ECG scheme presented in this article is based on sensing the variations in the electric potential close to the patient's relevant body surface. In order to measure the potential, suitable capacitive electrodes are designed and developed. The signal coupled from the active electrodes are amplified, filtered, digitized using NI myDAQ and displayed in a Virtual Instrument developed...
The incidence of cardiovascular diseases is rising, so more people are requiring cardiac services. The private service is very expensive; hence the public health sector capacity is exceeded to accomplish this demand. A proposal to solve this problem is the implementation of a wireless network based on Bluetooth (BT) for recording, monitoring and analysis of electrocardiographic signals (ECG). Three...
