A Wireless Sensor System for Reliable Recordings During Exercise

 描述（由申请人提供）：尽管最近无线传感器技术取得了进步，并且临床医生和研究人员对身体穿戴式测量系统的需求迅速增长，但当前技术在要求苛刻的应用期间保留了有限的功能，例如记录不受控制的运动障碍、体育活动或运动中的活动。 工作场所。需要在设计上取得突破，以产生一种可穿戴传感器技术，该技术可以在研究实验室范围之外记录高保真表面肌电（sEMG）信号，在研究实验室范围内发生剧烈或其他苛刻的条件。该项目开发了一种预商业化的体戴式数据采集系统，该系统专为在运动、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，这些传感器结合了联合收割机独特的设计元素（在第一阶段提供，在第二阶段实施），可提高传感器机电稳定性，并在苛刻的用例场景中提供无伪影性能。第二阶段还将增加一个“智能”便携式髋关节模块，用于采集和预览数据，并与一个平板电脑进行通信，该平板电脑被编程用于现场协议开发、信号质量检查和数据分析。该研究旨在开发一种低轮廓传感器，该传感器符合身体表面，提高户外使用的无线传输能力，并通过覆盖带和电极-皮肤界面提供上级肢体附着，减少运动伪影，并消除传感器摩擦衣服产生的静电伪影。髋关节模块将被开发用于无线配置网络中多达16个传感器，控制数据采集，并使数据可用于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，并为现场使用提供高级协议和分析功能。每个系统组件都代表了在可比的商业可用系统中没有发现的创新。在有问题的临床、运动和人体工程学应用期间，将在台架信号质量测试和人类受试者的用例场景中对系统组件进行测试。商业化前的开发将由研究和临床专家的独立反馈指导。我们将共同提供一个系统，实现性能指标无法达到在激烈的活动使用当前的技术。这项创新将扩大研究人员和临床医生在现实和无约束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。作为著名的Tibbetts奖的获得者，我们在SBIR成就方面有着良好的记录，以刺激满足联邦研发需求的技术创新，并成功地将该技术转移到市场。

 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.
