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.

描述（由申请人提供）：高级医学电子公司（AME）建议开发无线肌电图（EMG）集成电路（ICS），用于神经病理学中的研究和临床应用，例如小儿大脑麻痹，帕金森氏症，中风等。无线EMG应用程序的最先进的是收集到恒星拓扑中脱衣机放大器和发射器设备的EMG传感器的收集。固定在身体的连接线可能（1）限制身体运动，尤其是在儿童中，以及（2）添加噪音和/或运动伪像。基于建议的集成电路的传感器不会受到这些限制的影响，因为它们将在不需要电线的情况下局部放大，数字化和传输EMG信号，这在受试者正在运动的动态EMG测量中尤为重要。 1C技术的最新进展使AME能够设计和制造无线EMG IC，以整合EMG传感，信号调理，数字化，无线传输和电源采购的功能。通过粘合剂固定在皮肤上的电极软件包将能够通过无线网络传输数据到数据收集PC。 ICS将实施一个网络协议，该协议将支持多达16个独立的无线EMG传感器。在第一阶段，AME将完全指定1C要求，设计模拟构建块电路，设计自定义逻辑以实现无线网络协议并执行混合信号模拟。该项目的创新源于AME集成在单个IC上执行无线EMG数据收集所需的所有功能的能力。
