Abstract

A novel system which could measure blood pressure wirelessly through mobile phone has been proposed and developed. It consisted of a blood pressure signal recorder based on MCU (Micro Control Unit), which could transmit measured data via Bluetooth, and a software embedded on mobile phone, which could calculate the value of blood pressure and the rate of heart beat. The measurement results could easily be stored in text documents or in picture format. Detailed scheme and design of each module in the system was illustrated and experiments were conducted to demonstrate the reliability and stability of the device. A series of new conceptual explorations into blood pressure related issues were conducted with this system, including the variational blood pressure at different time periods in a day, the effect of posture on the measurement results and the impact of movements on blood pressure.
