To overcome the shortcomings of the existing pulse instruments

such as high cost and inconvenience to carry

a wireless portable detecting system for pulse condition is introduced which is based on traditional Chinese pulse-taking and mobile health care. The pulse signal is acquired by using piezoelectric thin-film sensor. It is filtered

amplified and lifted by the signal adjustment circuits. After A/D conversion in the STM32 F103 microcontroller

the baseline drift is eliminated by high-pass filtering and the burrs are erased by weighted moving average filtering. The signal is transmitted to the Android smart cell phone wirelessly via the HC—05 Bluetooth module.The signal waveform

the pulse rate and the pulse condition are shown on cell phone terminal. The test results show that the system has good characteristics of stability and accuracy. It is low cost

small size and lowpower consumption and it is convenient to use at home with alarm function.
