摘　　要：失重环境会造成骨质钙类流失,导致骨质状况显著下降,因此定期对骨质进行检测是必要的;针对传统骨质检测设备大多基于金属和半导体材料,柔韧性和可穿戴性较差且检测部位不全面的现状,提出一种基于便携式柔性超声传感器的人体骨骼状况检测系统;该系统采用定量超声和轴向检测理论,由超声传感器、FPGA控制电路和移动端APP构成,传感器封装改为柔性基底,能够全面检测身体的各个部位,在30名受试者的胫骨处进行实验测量;实验结果表明:该柔性超声骨质数据采集系统能量传递效率高达35%;在0.2 s内可完成检测和实时显示检测结果,误差小于0.3%;该系统在轻量化骨质检测系统领域有重要应用前景,有望取代传统骨质检测设备,为可穿戴器件的应用提供技术支持。Weightlessness environment can cause bone calcium loss,which will lead to a significant decline in bone condition.Therefore,it is necessary to detect bone regularly.In view of the fact that most traditional bone detection devices are based on metal and semiconductor materials,which have the situations of poor flexibility,low wearability and incomplete detection,a human bone condition detection system based on portable flexible ultrasonic sensors is proposed.The system is composed of an ultrasonic sensor,field programmable gate array(FPGA)control circuit and mobile APP.The sensor package is changed to a flexible substrate,which can comprehensively detect all parts of the body.Experimental measurement is carried out at the tibia of 30 volunteers.The experimental results show that the energy transfer efficiency of the flexible ultrasonic bone data acquisition system reaches by 35%,the detection and real-time display of the detection results can be completed within 0.2 s,and the detection error is less than 0.3%.This system has an important application prospect in the field of the lightweight bone detection system,which is expected to replace traditional bone detection equipment and provide a technical support for the application of wearable devices.
