 DESCRIPTION (provided by applicant): Despite recent advancements in wireless sensor technology and the rapidly growing need among clinicians and researchers for body-worn measurement systems, current technology retains limited functionality during demanding applications such as recording uncontrolled movement disorders, sports activities, or activities in the work place. A design breakthrough is needed to produce a wearable sensor technology that can record high- fidelity surface electromyographic (sEMG) signals outside the confines of the research laboratory, where vigorous or otherwise demanding conditions occur. This project develops a pre-commercial body-worn data acquisition system that is designed specifically for providing artifact-free sEMG signals when assessing muscle performance and kinematics during sports, neurology, rehabilitation, ergonomics, and home/community use. The system will consist of wireless sensors that combine unique design elements (provided in Phase I and implemented in Phase II), which improve sensor electromechanical stability and provide artifact-free performance during demanding use-case scenarios. Phase II will also add a 'smart' portable Hip Module for acquiring and previewing the data and communication with a Tablet programmed for in-field protocol development, signal quality checking, and data analysis. The research aims will develop a low profile sensor that conforms to the body surface, improves wireless transmission capability for outdoor use, and offers superior attachment to limbs through an overlay band and electrode-skin interface that reduces motion artifacts, and eliminates electrostatic artifacts produced by the sensor rubbing on clothing. The Hip Module will be developed to wirelessly configure up to 16 sensors in the network, control the data acquisition, and make the data available to the onboard screen and Tablet. Software development on the Tablet will support communication with the Hip Module and provide advanced protocol and analysis functions for field use. Each of the system components represent innovations not found in comparable commercially available systems. The system components will be tested during bench top signal quality tests and use-case scenarios among human subjects during problematic clinical, sports and ergonomic applications. The pre-commercial development will be guided by independent feedback from research and clinical experts. Together we will provide a system that achieves performance metrics unattainable during vigorous activities using current technology. The innovation will expand the ability of researchers and clinicians to investigate human movement and muscle function under realistic and unconstrained conditions. Our commercialization plan includes sufficient internal and external funding, and a sound marketing plan, to successfully transfer the technology to the marketplace. As a recipient of the prestigious Tibbetts award, we have a strong track record of SBIR achievements to stimulate technological innovation that meets Federal R&D needs, and successfully transfer this technology to the marketplace.

 描述（由申请人提供）：尽管无线传感器技术最近取得了进步，并且临床医生和研究人员对穿戴式测量系统的需求迅速增长，但当前的技术在要求苛刻的应用中保留了有限的功能，例如记录不受控制的运动障碍、体育活动或运动中的活动。 工作地点。需要在设计上取得突破，以生产一种可穿戴传感器技术，该技术可以在发生剧烈或其他苛刻条件的研究实验室范围之外记录高保真表面肌电 (sEMG) 信号。该项目开发了一种预商业化的穿戴式数据采集系统，专为在运动、神经病学、康复、人体工程学和家庭/社区使用期间评估肌肉性能和运动学时提供无伪影的 sEMG 信号而设计。该系统将由无线传感器组成，这些传感器结合了独特的设计元素（在第一阶段提供并在第二阶段实施），可提高传感器机电稳定性并在要求苛刻的用例场景中提供无伪影性能。第二阶段还将添加一个“智能”便携式髋关节模块，用于采集和预览数据，并与为现场协议开发、信号质量检查和数据分析而编程的平板电脑进行通信。该研究的目标是开发一种符合身体表面的薄型传感器，提高户外使用的无线传输能力，并通过覆盖带和电极-皮肤界面提供对四肢的卓越附着，减少运动伪影，并消除传感器在衣服上摩擦产生的静电伪影。 Hip 模块将被开发为无线配置网络中多达 16 个传感器、控制数据采集并将数据提供给机载屏幕和平板电脑。平板电脑上的软件开发将支持与髋关节模块的通信，并提供先进的协议和分析功能以供现场使用。每个系统组件都代表了同类商用系统中所没有的创新。系统组件将在有问题的临床、运动和人体工程学应用中的台式信号质量测试和人类受试者的用例场景中进行测试。商业化前的开发将受到研究和临床专家的独立反馈的指导。我们将共同提供一个系统，该系统可实现使用当前技术在剧烈活动中无法实现的性能指标。这项创新将扩大研究人员和临床医生在现实和不受约束的条件下研究人体运动和肌肉功能的能力。我们的商业化计划包括充足的内部和外部资金以及完善的营销计划，以成功地将技术转移到市场。作为享有盛誉的 Tibbetts 奖的获得者，我们在 SBIR 成就方面拥有良好的记录，能够刺激满足联邦研发需求的技术创新，并成功地将这项技术转移到市场。
