With the development of electronics, communications and materials technology, smart clothing or referred to as electronic textiles (E-Textile) are gradually moving from concept to practice. Reliable, safe and non-obtrusive wearable physiological monitoring is an important application field of smart clothing. Electrocardiogram (ECG) is a very important physiological parameters, but conventional ECG...
The experiments of formaldehyde (HCHO) removal from air were performed with photooxidation technology, adsorption technology, and photooxidation-adsorption technology respectively. According to results of experiments, the photooxidation-adsorption technology had the best removal efficiency of HCHO than two others, and the relative air humidity played an important role to these technologies. After...
The variability of pulse wave was found and discussed recently. The cross-correlation of variability of the parameters of pulse wave was studied in this paper. We found that the variability of the features in time was closely related. However, the variability of the features in time had little correlation with that of the amplitude features of pulse wave. The complexity of the variability of these...
The current health care system faces new challenge: increasing aging population, growing health cost, and mobile life. We present a kind of network architecture for Health Care Monitoring. This network named HCMNet integrates isolated wireless sensor networks (WSNs) into internet. Each WSN composed of health care sensors and one mesh router operates as a mobile ad-hoc network. Sensors can move in...
A new kind of wrist-worn health monitoring terminal is developed to realize multi-parameter measurement, wearing facilitates and reliable data transmission. The physiological parameters includes body temperature, pulse rate, breath rate and waveform, blood pressure, electrocardiograph(ECG), electroencephalogram(EEG) and the level of blood glucose real-timely. This terminal is designed by modules,...
A portable system to monitor environmental factors of pulmonary diseases is introduced in this paper. Disease triggers including temperature, humidity and airborne particles are continuously measured in real time. Data is transferred to a handheld device through a wireless body area network (BAN). If target triggers of disease are detected, the system will provide alarms and instructions to the patient...
Objective To evaluate the influence of monochrome LCDs with different resolutions on the detection performance of pulmonary nodules. Materials and Methods 93 chest images were selected, including 55 normal images and 38 positive images. Three high-, three mid-, and three low-experienced radiologists interpreted these images using three types of displays. Regarding the presence of nodule, five-point...
In this paper, we proposed a novel method of signal quality assessment of arterial blood pressure for monitoring Cerebral Autoregulation (CA). This method is based on algorithm of signal abnormality index (SAI). Two simple and effective features-end diastole slope sum (EDSS) and slow ejection slope sum (SESS), were proposed to identify abnormal beats from ABP as CA input in real-time. The methods...
To investigate the efficacy of Galvin, Bortfeld and Siochi leaf sequencing algorithm, a leaf sequencing optimization program that compares the results of typical clinical cases is presented. The output of this program is the number of segment and the total number of monitor unit of each clinical case based on the aforementioned three algorithms. Numerical results of each case are analyzed and tested...
Remote Home Monitoring System is one of important steps of the national medical and health system innovation. In this paper, we present a Remote Home Monitoring System (RHMS) which is consisted by the client side that in patients' houses and the server side that in hospitals. The key points are the design of client side software and multimedia interactive technology. The Visual C++ and SQL programming...
Objective: A minimum parameter set for the representation of body vital signs was extracted, in order to reduce the power consumption and improve the communication security of the data transmission in special scenarios such as battlefields and disaster fields. Methods: ECG, RESP, EEG, TEMP and Acceleration signals were investigated, and the accuracies across the different parameter sets of vital signs...
Extra-corporal Circulation Support Systems (ECCS) are used in cardiac surgery on a daily basis. Surgeons and perfusionists supervise patients' vital signals such as heart rate or blood pressure and ensure secure and errorless operation of the ECCS. Latest developments clear the way to use an ECCS for emergency circulatory resuscitation in non-clinical environments, even when trained staff is sparse...
In this paper, we present a portable intelligent electrocardiogram (ECG) monitoring system using the Zigbee wireless network technology. The system consist of both hardware and software development. For the hardware development, a Field Programmable Gate Arrays (FPGA), ECG sensor, preprocessing circuit, Zigbee transmission module, and external memory are used. And the FPGA with a Nios II soft-core...
This paper proposes design ideas for personalized medical testing technology of healthy smart home. The system architecture and design of physiological parameter detection sensors with wireless, low-costing and low power consumption are expounded. And the study of ECG monitoring in this system is presented to solve the key problem of ambulatory physiological parameter monitoring. Moreover, a design...
