脑电图（EEG）作为一种记录神经生理反应的技术出现于20世纪第二个十年。从那时起，维持信号采集探针（也称为电极）的物理原理几乎没有变化。目前，除了临床之外，技术的新进步带来了新的意想不到的应用领域，其中可用性和无凝胶操作等新方面是重中之重。由于材料和集成电子系统技术的新进展，新一代干电极已经开发出来以满足需求。在这篇文章中，我们回顾了目前用于临床和其他应用的干脑电图电极的开发方法，包括有关测量方法和评估报告的信息。我们得出的结论是，尽管在程序和方法上没有达成共识的情况下评估了广泛且非均匀的方法多样性，但它们的性能与湿电极所获得的性能相差不远，湿电极被认为是金标准，从而使前者成为各种新应用中的有用工具。
Electroencephalography (EEG) emerged in the second decade of the 20th century as a technique for recording the neurophysiological response. Since then, there has been little variation in the physical principles that sustain the signal acquisition probes, otherwise called electrodes. Currently, new advances in technology have brought new unexpected fields of applications apart from the clinical, for which new aspects such as usability and gel-free operation are first order priorities. Thanks to new advances in materials and integrated electronic systems technologies, a new generation of dry electrodes has been developed to fulfill the need. In this manuscript, we review current approaches to develop dry EEG electrodes for clinical and other applications, including information about measurement methods and evaluation reports. We conclude that, although a broad and non-homogeneous diversity of approaches has been evaluated without a consensus in procedures and methodology, their performances are not far from those obtained with wet electrodes, which are considered the gold standard, thus enabling the former to be a useful tool in a variety of novel applications.
