We have designed and fabricated an anatomically accurate human head phantom that is capable of generating realistic electric scalp potential patterns. This phantom was developed for performance evaluation of new electroencephalography (EEG) caps, hardware, and measurement techniques that are designed for environments high in electromagnetic and mechanical noise. The phantom was fabricated using conductive composite materials that mimic the electrical and mechanical properties of scalp, skull, and brain. The phantom prototype was calibrated and testing was conducted using a 32-electrode EEG cap. Test results show that the phantom is able to generate diverse scalp potential patterns using a finite number of dipole antennas internal to the phantom. This phantom design could provide a valuable test platform for wearable EEG technology.
我们设计并制作了一个解剖学精确的人头模型，能够产生逼真的头皮电潜在模式。该模型是为评估新的脑电图（EEG）帽、硬件和测量技术而设计的，这些技术旨在用于电磁和机械噪声较高的环境。该模型使用导电复合材料制成，可模拟头皮、颅骨和大脑的电和机械特性。使用一个 32 电极的 EEG 帽对模型原型进行了校准和测试。测试结果表明，该模型能够使用模型内部的有限数量的偶极天线产生各种头皮电位模式。这种模型设计可以为可穿戴 EEG 技术提供一个有价值的测试平台。
