DESCRIPTION (provided by applicant): The goal of this NIH Phase II proposal is to develop, fabricate and clinically test a dry micro-machined physiologic recording electrode that can be used without requiring electrolytes and/or skin preparation. Traditionally, the monitoring of human physiological data requires attaching electrodes to the skin with adhesive collars, tape, or collodion after the skin has been vigorously cleaned to reduce electrical contact impedance. This approach is both time-consuming and troublesome. Therefore, a need exists for physiological recording electrodes that do not require exorbitant technician set-up time and vigorous skin preparation of the patient to be monitored. The proposed dry physiological recording electrodes have an innovative micro-machined surface that enables fast application times without causing patient discomfort. Recent tests showed the feasibility of producing micro-topographical features on the dry electrode surface that penetrate through the high impedance dead skin cells making excellent electrical contact with the patient even on hairy parts of the test subject. The recorded physiological signals (EEG and EMG) were comparable to adjacently mounted conventional electrodes. This Phase II program will optimize and further develop micro-machined electrodes to collect EEG, EMG, EOG, ECG, etc, from a variety of patients regardless of skin thickness and amount of hair.

描述（由申请人提供）：该NIH II期建议的目的是开发，制造和临床测试干燥的微型生理记录电极，无需电解质和/或皮肤准备就可以使用。传统上，对人体生理数据的监测需要在剧烈清洁皮肤后用粘合项，胶带或胶结将电极连接到皮肤上，以减少电接触阻抗。这种方法既耗时又麻烦。因此，存在不需要高昂的技术人员设置时间和患者的皮肤准备时间的生理记录电极的需求。拟议的干燥生理记录电极具有创新的微型机械表面，可在不引起患者不适的情况下快速应用时间。最近的测试表明，在干燥电极表面上产生微观图特征的可行性，该特征穿过高阻抗死皮细胞，即使在测试受试者的毛茸茸的部分也可以与患者进行良好的电气接触。记录的生理信号（EEG和EMG）与相邻安装的常规电极相当。该阶段II计划将优化并进一步开发微置的电极，以收集各种患者的脑电图，EMG，EOG，ECG等，无论皮肤厚度和头发量如何。
