We describe a flexible wireless neural recording system, which is comprised of a 15-channel analog FM transmitter, digital receiver and custom user interface software for data acquisition. The analog front-end is constructed from commercial off the shelf (COTS) components and weighs 6.3g (including batteries) and is capable of transmitting over 24 hours up to a range over 3m with a 25microV(rms) in-vivo noise floor. The Software Defined Radio (SDR) and the acquisition software provide a data acquisition platform with real time data display and can be customized based on the specifications of various experiments. The described system was characterized with in-vitro and in-vivo experiments and the results are presented.
我们描述了一种灵活的无线神经记录系统，它由一个15通道模拟调频发射器、数字接收器和用于数据采集的定制用户界面软件组成。模拟前端由商用现货（COTS）组件构建而成，重6.3克（包括电池），能够在25微伏（均方根值）的体内本底噪声下，传输超过24小时，传输范围超过3米。软件定义无线电（SDR）和采集软件提供了一个具有实时数据显示的数据采集平台，并且可以根据各种实验的规格进行定制。所描述的系统通过体外和体内实验进行了表征，并展示了实验结果。
