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.

描述（由申请人提供）：Advanced Medical Electronics寻求开发一种用于无线采集高密度表面肌电图（HD sEMG）信号的可穿戴设备。一种称为超宽带（UWB）的新无线网络标准使得创建一种可以真实的传输128个或更多通道数据的流动研究HD表面肌电信号仪器成为可能。高密度表面肌电信号是一种非侵入性的过程，用于测量肌肉活动，其中多个（60至128个）紧密间隔的电极覆盖在皮肤的限定区域上。除了时间活动之外，HD sEMG还允许研究空间EMG活动（这在检测新的肌肉特征方面具有前景），提供肌纤维传导速度（MFCV）测量以及单个运动单位（MU）特征的评估。HD表面肌电图的最新研究已经导致薄的柔性多电极网格的开发，其改进了早期笨重和刚性的电极布置。然而，来自这些多电极网格的信号的电子采集目前需要连接到庞大放大器的离体电缆组件。本项目旨在开发一种可穿戴的HD表面肌电信号采集模块。该模块将具有能够发射128个或更多信道的UWB无线电，这些信道由高分辨率模数转换器采样。所获得的宽带高分辨率信号将使研究人员在处理和分析HD sEMG数据时具有最大的灵活性。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EMG活动，这在检测新的肌肉特征方面具有前景，提供肌纤维传导速度测量和单个运动单元特征的评估。
