A Wearable Device for Wireless Acquisition of High Density Surface EMG Signals

描述（由申请人提供）：先进医疗电子寻求开发一种可穿戴设备，用于无线采集高密度表面肌电图（HD sEMG）信号。一种被称为超宽带（UWB）的新型无线网络标准使得创建一种可以实时传输128个或更多通道数据的动态研究高清表面肌电信号仪器成为可能。高密度肌电图是一种非侵入性的测量肌肉活动的方法，使用多个（60到128）紧密间隔的电极覆盖在特定的皮肤区域上。除了时间活动，HD表面肌电信号还允许研究空间肌电信号活动（这在检测新的肌肉特征方面有希望），提供肌纤维传导速度（MFCV）测量，以及单个运动单元（MU）特征的评估。最近对高清表面肌电信号的研究导致了薄柔性多电极网格的发展，这改善了早期笨重和僵硬的电极排列。然而，从这些多电极网格中电子采集信号目前需要连接到笨重放大器的离体电缆组件。该项目旨在开发一种用于高清肌电信号采集的可穿戴模块。该模块将具有一个UWB无线电，能够通过高分辨率模拟数字转换器传输128或更多通道采样。所获得的宽带高分辨率信号将使研究人员在处理和分析高清表面肌电信号数据方面具有最大的灵活性。该项目旨在开发一种可穿戴设备，用于无线采集高密度表面肌电图（EMG）信号。该设备将允许研究时间和空间肌电图活动，这在检测新的肌肉特征方面具有前景，提供肌肉纤维传导速度测量和单个运动单元特征的评估。

DESCRIPTION (provided by applicant): Advanced Medical Electronics seeks to develop a wearable device for the wireless acquisition of high-density surface-electromyogram (HD sEMG) signals. A new wireless networking standard called ultra-wideband (UWB) makes possible the creation of an ambulatory research HD sEMG instrument that can transmit 128 or more channels of data in real time. High-density sEMG is a non-invasive process for measuring muscle activity with multiple (60 to 128) closely spaced electrodes overlying a defined area of the skin. In addition to temporal activity, HD sEMG also allows spatial EMG activity to be studied (which holds promise in the detection of new muscle characteristics), provides muscle fiber conduction velocity (MFCV) measurements, and the evaluation of single motor unit (MU) characteristics. Recent research in HD sEMG has resulted in the development of thin flexible multi-electrode grids which improves upon earlier bulky and stiff electrode arrangements. However the electronic acquisition of the signals from these multi-electrode grids currently requires off-body cable assemblies connected to bulky amplifiers. This proposed project seeks to develop a wearable module for HD sEMG signal acquisition. The module will have a UWB radio capable of transmitting 128 or more channels sampled with high resolution analog to digital converters. The acquired wide-band high resolution signals will allow researchers maximum flexibility in the processing and analysis of HD sEMG data. This project seeks to develop a wearable device for the wireless acquisition of high-density surface- electromyogram (EMG) signals. The device will allow temporal and spatial EMG activity to be studied, which holds promise in the detection of new muscle characteristics, provides muscle fiber conduction velocity measurements and the evaluation of single motor unit characteristics.
