Design and realization of pulse signal test system bases on bluetooth transmission

A pulse signal test system based on wireless bluetooth transmission was designed,in which a PVDF pulse sensor,signal modulation circuit,data acquisition circuit,blue tooth wireless transmission module and displaying module for data received from single-chip computer were included.The test result showed that the system could acquire real-time pulse signal of human being,the data was then sent to mobile phone programmed with J2ME language through wireless bluetooth,the received signal wave form could be displayed on the mobile phone and processed further as well,so that the remote supervision could be realized.
