An Implantable Wireless Myoelectric Sensor for Prosthetic Control

描述（由申请人提供）：拟议的项目旨在创建一个完全植入式肌电传感器系统，包括假肢或神经假肢设备的无线接口。现代肌电假肢中的表面电极通常嵌入假肢接受腔中并与皮肤接触。这些电极检测并放大来自残肢中肌肉的自主收缩的肌肉动作电位，并且这些电信号控制假肢的运动和功能。存在许多与外部电极相关的性能相关缺陷，包括维持足够的肌电图（EMG）信号幅度、外来噪声采集和适当的电极接口维护，这些缺陷预计将使用植入式传感器得到改善或解决。拟议项目将利用微电子和纳米技术领域的新技术应用于假肢控制的植入式无线信号采集。拟议的植入技术将允许假肢制造商提供具有更高性能、能力和患者舒适度的产品。在第一阶段，KBT将建立一个原型无线模块，设计为一个完全植入的生物电位传感器，以捕获信号，如肌内肌电图。第二阶段的工作将集中在设计改进上，目标是小型化、包装和人体试验。拟议项目将利用微电子和纳米技术领域的新技术，应用于假肢控制的植入式无线信号采集。拟议的植入技术将允许假肢制造商提供具有更高性能、能力和患者舒适度的产品。

DESCRIPTION (provided by applicant): The proposed project seeks to create a fully-implantable myoelectric sensor system that includes a wireless interface to prosthetic limbs or neural prosthetic devices. Surface electrodes in modern myoelectric prosthetics are often embedded in the prosthesis socket and make contact with the skin. These electrodes detect and amplify muscle action potentials from voluntary contractions of the muscle in the residual limb and these electrical signals control the prosthetic's movement and function. There are a number of performance-related deficiencies associated with external electrodes including the maintenance of sufficient electromyogram (EMG) signal amplitude, extraneous noise acquisition, and proper electrode interface maintenance that are expected to be improved or solved using implanted sensors. The proposed project will leverage new technologies within the microelectronics and nanotechnology fields for application to implantable wireless signal acquisition for prosthetic control. The proposed implanted technology will allow prosthetic limb manufacturers to provide products with increased performance, capability, and patient-comfort. In Phase I, KBT will build a prototype wireless module designed as a fully-implanted biopotential sensor to capture signals such as intramuscular EMG. The Phase II efforts will concentrate on design enhancements with a goal towards miniaturization, packaging, and human trials. The proposed project will leverage new technologies within the microelectronics and nanotechnology fields for application to implantable wireless signal acquisition for prosthetic control. The proposed implanted technology will allow prosthetic limb manufacturers to provide products with increased performance, capability, and patient-comfort.
