“…The pulse signal is very closely associated with disease, and it is very meaningful for the treatment based on syndrome differentiation. The pulse signal acquisition instrument is the necessary toll for the research of pulse signal, and it can subjectively, exactly and real-time describe the pulse information, and offer scientific references for the impersonality, quantification and standardization of pulsetaking [1][2][3].…”

The pulse signal is a sort of important human physiological signal. A pulse signal acquisition system based on the virtual instrument technology is developed. The system is composed of two parts, i.e. the data acquisition equipment taking single chip microcomputer (SCM) as the core hardware and the data processing system based on LabView software on the computer. The integrated pulse sensor based on PVDF piezoelectric film is selected to translate the pulse jumpiness of checking object into electric signal which could be disposed. The feeble signals of sensor are amplified through the preamplifier and post-amplifier and filtered by active high pass filter and low pass filter. Those signals are translated into digital pulse signals by the analog to digital converter, and input computer by the serial port of SCM. Finally LabView software displays, records, save and process these signals. The pulse acquisition system based on virtual instrument could make the design become simpler and more modularization. The user interface is more friendly and convenient to operation and using.
