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.
一种能够通过手机无线测量血压的新型系统已被提出并研发出来。它由一个基于微控制单元（MCU）的血压信号记录器和手机上嵌入的软件组成，血压信号记录器能够通过蓝牙传输测量数据，手机软件则可以计算血压值和心率。测量结果能够轻松地以文本文件或图片格式存储。文中阐述了该系统各模块的详细方案和设计，并进行了实验以证明该设备的可靠性和稳定性。利用该系统对与血压相关的问题进行了一系列新的概念性探索，包括一天中不同时间段的血压变化、姿势对测量结果的影响以及运动对血压的影响。
