The real-time detection of pulse signal has important meaning for the early discovering and treatment of heart diseases. A novel pulse signal-recording instrument based on system-on-chip and separated universal serial bus (USB) interface chip is developed. The hardware system and application software are designed and the whole principle of various details in the device is described. The system selects the integrated pulse sensor based on PVDF piezoelectric film to convert the pulse jumpiness of measured object into disposal electric signals. Then the system uses MSP430F system-on-chip with high integration to control and realize the acquisition, amplifying, filtering and analogy-to-digital conversion of pulse signals. Finally it records the pulse signals in the flash disk memorizer through separate USB interface chip CH375 after compressing and coding by two-sample value adaptive algorithm. The system has many advantages such as small volume, convenient usage and strong function. It can be taken portably.
