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型的电子学和微生物技术，以创建一个无创的，研究平台，用于靶向刺激和表征人类外周神经。该II期建议涉及高分辨率周围神经接口的两个重要发展。 AIM 1将发展高分辨率和低噪声皮肤表面电极阵列。阵列内的每个电极都包含具有成本效益的微图案针头，这可以通过疼痛（不止痛）刺穿皮肤的最高层来显着降低电极阻抗，从而在不牺牲信号效果比率的情况下提供高空间分辨率。 AIM 2将开发微型刺激并记录电子设备，以恢复受刺激伪像的传统掩盖的信号。恢复的数据，结合了与数十个皮肤表面电极同时相互作用的能力，将允许非侵入性映射，表征和外周神经控制。除了减少监测和操纵周围神经所需的复杂性，疼痛和训练外，该平台还将允许疾病诊断，表面肌电图，神经假体，术中监测和治疗性刺激进行持续创新。
