DESCRIPTION (provided by applicant): The proposed study combines novel electronics and microfabrication techniques to create a non-invasive, research platform for targeted stimulation and characterization of human peripheral nerves. This Phase II proposal involves two significant developments for high-resolution peripheral nerve interfacing. Aim 1 will develop high-resolution and low-noise skin surface electrode arrays. Each electrode within the array will consist of cost-effective micropatterned needles, which significantly decrease electrode impedance by pain- lessly piercing the topmost layer of skin, thereby providing high spatial resolution without sacrificing signal- to-noise ratio. Aim 2 will develop miniaturized stimulation and recording electronics to recover signals tra- ditionally obscured by stimulation artifacts. The recovered data, combined with the ability to simultaneously interact with dozens of skin-surface electrodes, will allow non-invasive mapping, characterization, and con- trol of peripheral nerves. In addition to reducing the complexity, pain, and training required to monitor and manipulate peripheral nerves, this platform will allow for continued innovation in disease diagnostics, sur- face electromyography, neural prosthetics, intraoperative monitoring, and therapeutic stimulation.

描述（由申请人提供）：拟议的研究结合了新颖的电子学和微加工技术，创建了一个非侵入性研究平台，用于人类周围神经的定向刺激和表征。该第二阶段提案涉及高分辨率周围神经接口的两项重大进展。目标 1 将开发高分辨率和低噪声的皮肤表面电极阵列。阵列中的每个电极将由经济高效的微图案针组成，这些针通过无痛刺穿皮肤最上层来显着降低电极阻抗，从而在不牺牲信噪比的情况下提供高空间分辨率。目标 2 将开发小型化刺激和记录电子设备，以恢复传统上被刺激伪影掩盖的信号。恢复的数据加上同时与数十个皮肤表面电极交互的能力，将允许对周围神经进行非侵入性绘图、表征和控制。除了减少监测和操作周围神经所需的复杂性、疼痛和培训之外，该平台还将允许疾病诊断、表面肌电图、神经修复、术中监测和治疗刺激方面的持续创新。
