Novel System for EMG Instrumentation

描述(由申请人提供)：先进医疗电子公司(AME)建议开发无线肌电(EMG)集成电路(IC)，用于研究和临床应用于神经病理，如儿童脑瘫、帕金森、中风等。目前最先进的无线EMG应用是收集连接到身体佩戴的放大器和发射器设备的星形拓扑结构的EMG传感器。固定在身体上的连接线可以(1)限制身体移动，尤其是儿童，以及(2)增加噪声和/或运动伪影。基于提出的集成电路的传感器不会受到这些限制，因为它们将在不需要电线的情况下对EMG信号进行本地放大、数字化和传输，这在对象处于运动状态的动态EMG测量中尤其重要。1C技术的最新进展使AME能够设计和制造无线肌电IC，将肌电传感、信号调理、数字化、无线传输和电源功能集成到非常小的电极封装中。通过粘合剂将电极包固定在皮肤上，将能够通过无线网络将数据传输到数据采集PC。这些集成电路将实施一种网络协议，支持多达16个独立的无线肌电传感器。在第一阶段，AME将完全指定1C要求，设计模拟积木电路，设计用于实现无线网络协议的定制逻辑，并执行混合信号模拟。该项目的创新源于AME能够在单个IC上集成执行无线肌电数据采集所需的所有功能。

DESCRIPTION (provided by applicant): Advanced Medical Electronics Corporation (AME) proposes to develop wireless electromyography (EMG) integrated circuits (ICs) for research and clinical applications in neurological pathologies, such as pediatric cerebral palsy, Parkinson's, stroke, etc. The current state-of-the-art for wireless EMG applications is collection of EMG sensors wired to a body-worn amplifier and transmitter device in a star topology. The connecting wires, which are secured to the body, may (1) restrict body movement, especially with children, and (2) add noise and/or motion artifacts. Sensors based on the proposed integrated circuit will not suffer from these limitations since they will locally amplify, digitize and transmit EMG signals without the need for wires, which is of particular importance in dynamic EMG measurements where the subject is in motion. Recent advances in 1C technology enable AME to design and fabricate wireless EMG ICs that integrate the functions of EMG sensing, signal conditioning, digitizing, wireless transmission, and power sourcing into a very small electrode package. An electrode package held to the skin by adhesive will be able to transmit the data via a wireless network to a data collection PC. The ICs will implement a network protocol that will support up to 16 independent wireless EMG sensors. In phase I, AME will completely specify the 1C requirements, design the analog building block circuits, design the custom logic to implement the wireless network protocol, and perform mixed signal simulations. This project's innovation stems from AME's ability to integrate all the functions necessary to perform wireless EMG data collection on a single IC.
