摘　　要：本文介绍了一种基于射频技术的穿戴式医疗仪器的设计。该设计采用nRF905射频芯片实现生理信号的无线传输。同时,相对于其它类似研究,本设计充分考虑了用户生理信息无线传输时的安全性,在数据传输前进行了AES加密处理。最后,在实验中对心电和脉搏波进行了监测,实验结果表明本设计能够实现生理信号实时、安全、准确的无线传输。A design based on radio technology for wearable medical device is presented in this paper. The design applies nRF905 radio-chip to implement the wireless transmission of physiological signals. In contrast to other similar research, the design fully considers the client＇ s privacy in healthy information during wireless transmission. An AES encryption algorithm is employed before the transmission. At last, an experiment for monitoring ECG and Pulse is carried out, and the result shows that the design can successfully offer a real-time, secure and exact wireless transmission for physiological signals.
