表面肌电图广泛应用于许多领域来推断人类意图。然而，传统电极不适合长期测量，且容易受环境影响，因此sEMG的应用范围受到限制。在本文中，我们提出了一种柔性带集成、弯曲微针阵列电极，用于稳健的长期测量、高选择性和易于应用。对信号质量、长期可用性和对出汗的敏感性进行了研究。还评估了其运动辨别性能。结果表明，所提出的电极对汗水具有鲁棒性，并且可以保持超过 8 小时的高质量测量能力。与商用湿电极和干电极相比，所提出的电极还具有高运动选择性。
Surface electromyography is widely used in many fields to infer human intention. However, conventional electrodes are not appropriate for long-term measurements and are easily influenced by the environment, so the range of applications of sEMG is limited. In this paper, we propose a flexible band-integrated, curved microneedle array electrode for robust long-term measurements, high selectivity, and easy applicability. Signal quality, in terms of long-term usability and sensitivity to perspiration, was investigated. Its motion-discriminating performance was also evaluated. The results show that the proposed electrode is robust to perspiration and can maintain a high-quality measuring ability for over 8 h. The proposed electrode also has high selectivity for motion compared with a commercial wet electrode and dry electrode.
