Abstract

We propose a novel neuromodulation (NM) interface with true 100mV pp linear input range that enables concurrent neural sensing and stimulation. It includes a flexible 4-driver-to-32-contact stimulator that can deliver up to 3.1mA per driver (total 12.4mA) and a 32-channel sensing unit. This 32-channel interface meets design requirements of human-quality implants at unprecedented electronic miniaturization (20x reduction) as compared to prior art. It offers major new clinical perspectives: always-on sensing for enhanced closed-loop therapy, multi-channel arbitrary stimulation waveforms with user-friendly programming, and a high spatial resolution neural interface for precise target localization.

一个真正的全双工32通道0.135cm3神经接口

我们提出了一种新颖的神经调节(NM)接口，具有真正的100mV pp线性输入范围，可以同时实现神经传感和刺激。它包括一个灵活的4驱动器到32触点刺激器，每个驱动器可提供高达3.1mA(总12.4mA)和一个32通道传感单元。与现有技术相比，这种32通道接口以前所未有的电子小型化(缩小20倍)满足人体质量植入物的设计要求。它提供了主要的新临床前景:用于增强闭环治疗的始终在线传感，具有用户友好编程的多通道任意刺激波形，以及用于精确定位目标的高空间分辨率神经接口。
