Bioelectric sensor and its application in medical signal acquisition

As the cornerstone of the bridge between life science and mechatronics, bioelectrical sensors have made significant progress in various scientific fields in recent years. Despite some drawbacks, this sensor distinguishes itself from others in the sense of its revolutionary sensitivity and accuracy. This paper will start from summarizing their existing technologies in the fields of medical treatment, environmental monitoring, industrial manufacturing and agricultural production, and discussing their breakthrough achievements in frontier science. Then, this paper will focus on the analysis of the research results of bioelectrical sensors in the acquisition of ECG, EEG and EMG signals, respectively emphasizing their high-precision, high resolution and immediacy, which are essential for modern medicine to detect human signals. Additionally, the paper will briefly discuss some recentpopular technologies, such as enhancing the comfort of patients wearing ECG monitoring equipment, as well as the fields favored by cutting-edge science - brain computer interface and the new bionic structure of EMG sensors, giving a comprehensive understanding of bioelectric sensors.
