title: [A novel respiratory detecting system based on bio-impedance].
abstract: This paper introduces the design and implementation of a novel respiratory detecting system based on bio-impedance method. By increasing electrodes in space, the system make multi-channel respiratory signals be superpositioned and filtered (SNR); Traditional filter methods by both hardware and software are also used to further increase anti-interference ability. A low consumption and portable instrument is designed based on MSP430 Micro Controller Unit (MCU), The experiment shows a better performance in the reduction of interference noises of heartbeat and blood flow especially the motion artifact. Also the system works stably.
