Objective To develop an electronic sphygmomanometer with accurate and reliable measuring results and intuitive measuring processes. Methods The meter took STM32F103RBT6 as the main control chip, INA122 and OPA333 as the operational amplifier, and KEIL＇s RVMDK3.8 as the software design platform. Results A manometric waveform-based electronic sphygmomanometer was designed with STM32 microprocessor as the core and oscillography to measure human blood pressure. Conclusion The sphygmomanometer can measure blood pressure and display the oscillogram of vascular elasticity at real time.
