A novel wearable physiological monitoring system is presented in this paper. The related signal and noise characteristics obtained by the system under electromagnetic and body motion interferences are analyzed and the performance of the active electrode circuit is assessed. It is concluded that the active electrode can eliminate the noise caused by electromagnetic interference significantly, but has...
A textile-based breath-sensing system and the testing results with different postures are described. Two electrodes are placed on a belt, loosely buckled for user comfort, to charge and discharge a capacitor modeled off human movement of breathing. For most conditions of daily activities, the system has demonstrated capable of providing accurate measurement of respiratory rates.
