Abstract

Wearable electromyography devices can detect muscular activity for health monitoring and body motion tracking, but this approach is limited by weak and stochastic signals with a low spatial resolution. Alternatively, echomyography can detect muscle movement using ultrasound waves, but typically relies on complex transducer arrays, which are bulky, have high power consumption and can limit user mobility. Here we report a fully integrated wearable echomyography system that consists of a customized single transducer, a wireless circuit for data processing and an on-board battery for power. The system can be attached to the skin and provides accurate long-term wireless monitoring of muscles. To illustrate its capabilities, we use this system to detect the activity of the diaphragm, which allows the recognition of different breathing modes. We also develop a deep learning algorithm to correlate the single-transducer radio-frequency data from forearm muscles with hand gestures to accurately and continuously track 13 hand joints with a mean error of only 7.9°.

基于单个传感器的可穿戴超声造影系统

可穿戴肌电图设备可以检测肌肉活动，用于健康监测和身体运动追踪，但这种方法受到信号微弱、随机、空间分辨率低的限制。另外，超声波肌电图可利用超声波检测肌肉运动，但通常依赖于复杂的传感器阵列，这些阵列体积大、功耗高，而且会限制用户的移动性。在此，我们报告了一种完全集成的可穿戴式超声肌成像系统，该系统由一个定制的单传感器、一个用于数据处理的无线电路和一个板载电源电池组成。该系统可以贴在皮肤上，对肌肉进行长期精确的无线监测。为了说明其功能，我们使用该系统检测横膈膜的活动，从而识别不同的呼吸模式。我们还开发了一种深度学习算法，将前臂肌肉的单传感器射频数据与手势相关联，从而准确、连续地跟踪 13 个手部关节，平均误差仅为 7.9°。
