Low-power wearable ECG monitoring system for multiple-patient remote monitoring

Abstract : Many devices and solutions for remote ECG monitoring have been proposed in the literature. These solutions typically have a large marginal cost per added sensor and are not seamlessly integrated with other smart home solutions. Here we propose an ECG remote monitoring system that is dedicated to non-technical users in need of long-term health monitoring in residential environments and is integrated in a broader Internet of-Things (IoT) infrastructure. Our prototype consists of a complete vertical solution with a series of advantages with respect to the state of the art, considering both prototypes with integrated front end and prototypes realized with off-the-shelf components: i) ECG prototype sensors with record-low energy per effective number of quantized levels, ii) an architecture providing low marginal cost per added sensor/user, iii) the possibility of seamless integration with other smart home systems through a single internet-of-things infrastructure.

 EXISTING SYSTEM :

 ? We introduce the relative investigation of all with past existing methodology. ? Strength of matured individuals should be checked all the more often, which represents a more noteworthy challenge to existing clinical framework. ? An electrocardiogram gadget screens the cardiovascular status of a patient by recording the heart's electrical potential versus time. ? Such gadgets assume a vital part to save the existence of patients who endure a respiratory failure or experience the ill effects of these patients. ? The gadget requires a few links associated with a patient of which influences the existence nature of a tolerant.

 DISADVANTAGE :

 ? The disadvantage of this system is it increases cost per patient. ? However, power consumption mostly in such sensors is mainly due to the radio link and therefore the optimization obtained by the use of the dedicated front-end has a limited impact on the power performance of the complete sensor. ? Most non-industrial nations have very helpless data about these medical services issues. ? One such clinical issue which is normal and requires standard checking is pulse. ? The current of the analog circuit results in low slew rate and problems of large signal performance of the system.

 PROPOSED SYSTEM :

 • In this paper we proposed an efficient system which is able to check ECG and send data to the webserver. Our proposed approach is do the proper justice with Cost, Size, power & Efficiency parameters. • The proposed ultra-low power ECG monitoring system provides a convenient everyday monitoring both for the patients and their physicians. • This robust system enables the users to track their hearts'signals even during intensive physical activities by removing the motion artifacts and filtering the external noises. • Some of the proposed ECG sensor nodes are based on a dedicated integrated front end, that sometimes includes a DSP, and require a second off-the-shelf chip to implement the radio link.

 ADVANTAGE :

 ? Our system instead, is based on a general-purpose, high performance, high resolution, low power ADC (Texas Instruments ADS1246)that also includes a digital filter. ? Recent advances in microelectronics and in communication protocols enable cost reduction and performance improvement in these systems, both at the level of individual sensors, and at the level of the infrastructure. ? When compared with fully integrated solutions, our circuit performance are better in terms of CMRR, input noise and ENOB. ? We would like to stress the fact that a dedicated front-end chip is not enough to achieve an advantage in terms of overall sensor performance.
