针对人们对人体运动状态监测的需求,设计了基于微机电系统(micro electro mechanical systems,简称 MEMS)数字输出加速度传感器 ADXL345与超低功耗单片机 MSP430F169的计步手环和基于 Android 系统的手机应用程序(APP)。该手环用传感器 ADXL345采集人体行走时的加速度信息,利用矢量求和算法实现计步功能,并估算行走过程中的热量消耗；手环通过蓝牙方式与 Android 手机通信,从而在手机上实现计步数据与卡路里消耗的显示,并可在手机上对手环的DS1337时钟芯片进行闹钟设置。通过对2名男性和2名女性分别进行60 s 步行测试,测试结果表明,该系统运行可靠,计步算法适应性良好,具有体积小、功耗低、工作稳定、计步准确、人机交互友好等特点。
