目的：研制一种对皮肤电位变化（SPV）不敏感的干电极，以消除SPV的干扰。研究方法：在传统的微针阵列电极的基础上，在微针的根部涂覆一层聚对二甲苯膜，以使电极与角质层绝缘。只有针尖外露，使其能直接与生发层接触。结果：皮肤电位不会耦合到记录电极。因此，SPV不会影响动态下的生物电位记录。结论：所提出的电极是对来自SPV的运动噪声源不敏感的设备的潜力。重要性：为干电极在抗运动干扰能力强的可穿戴技术中的应用奠定了基础。
Objective: A skin-potential variation (SPV) insensitive dry electrode is developed to remove the interference of SPV. Methods: Based on a conventional microneedles array-based electrode, a layer of Parylene membrane is coated at the root of microneedles to insulate the electrode from the corneum layer. Only tips of the needles are exposed to make it can contact with the stratum germinativum layer directly. Results: As a result, skin potential will not be coupled into the recording electrode. Thus, SPV will not influence the biopotential recording in the dynamic state. Conclusion: The proposed electrode is potential for a device which is insensitive to the motion noise source from SPV. Significance: It paves the way for applications of the proposed dry electrode in the wearable technology which require strong anti-motion interference ability.
