Electroencephalography (EEG) is an important biopotential, and has been widely applied in clinical applications. The conventional EEG electrode with conductive gels is usually used for measuring EEG. However, the use of conductive gel also encounters with the issue of drying and hardening. Recently, many dry EEG electrodes based on different conductive(More)
Real-time monitoring of cardiac health is helpful for patients with cardiovascular disease. Many telemedicine systems based on ubiquitous computing and communication techniques have been proposed for monitoring the user's electrocardiogram (ECG) anywhere and anytime. Usually, wet electrodes are used in these telemedicine systems. However, wet electrodes(More)
A new water-soluble polysaccharide (longan polysaccharide 1 (LP1)) was extracted and successfully purified from Dimocarpus longan pulp via diethylaminoethyl (DEAE)-cellulose anion-exchange and Sephacryl S-300 HR gel chromatography. The chemical structure was determined using Infrared (IR), gas chromatography (GC) and nuclear magnetic resonance (NMR)(More)
Compared with the original system that has unidirectional broadcasting characteristics, the interactive satellite remote education system which based on DTN greatly improved. However, in the special application environment of the satellite remote education system, the traditional Internet security mechanism can't meet the DTN security needs. In order to(More)
Electrocardiography (ECG) is a kind of electrical activities of the heart measured along the skin, and is also an important tool to diagnosis heart decease. In clinical, the conventional ECG electrode is generally used for measuring ECG signal. However, it requires skin preparation and conductive gels to reduce the impedance of the skin-electrode interface.(More)
