脑电图（EEG）是神经系统疾病和功能障碍（例如癫痫和失眠）的常用诊断工具。然而，由于所需的复杂的皮肤准备程序和不方便的脑电图数据采集系统，当前的脑电图技术无法在护理点快速方便地使用。这项工作提出了一种便携式放大器设计，集成了一组皮肤螺旋电极和无线数据链路。电池供电放大器包含一个仪表放大器、两个非反相放大器、两个高通滤波器和一个低通滤波器。它能够将脑电信号放大10000倍以上，并且具有高阻抗、低噪声、体积小、重量轻的特点。我们的电极和放大器非常适合现场护理应用，特别是在运送患有创伤性脑损伤或中风的患者期间。
The Electroencephalography (EEG) is a common diagnostic tool for neurological diseases and dysfunctions, such as epilepsy and insomnia. However, the current EEG technology cannot be utilized quickly and conveniently at the point of care due to the complex skin preparation procedures required and the inconvenient EEG data acquisition systems. This work presents a portable amplifier design that integrates a set of skin screw electrodes and a wireless data link. The battery-operated amplifier contains an instrumentation amplifier, two non-inverting amplifiers, two high-pass filters, and a low-pass filter. It is able to magnify the EEG signals over 10,000 times and has a high impedance, low noise, small size and low weight. Our electrode and amplifier are ideal for point-of-care applications, especially during transportation of patients suffering from traumatic brain injury or stroke.
