Bioelectric instrument is a scientific instrument for measuring human and animal electrical signals. It can collect bioelectric signal data of chest and head area, such as EEG and ECG, so as to study human health and disease diagnosis. The bioelectricity instrument mainly converts electrical signals into digital signals through electrodes attached to the patient's body surface, and processes and analyzes the signals.

Bioelectric instruments are widely used in medical research and clinical diagnosis. For example, through the analysis of EEG, we can study the relationship between brain neuron activity and cognitive ability, learning ability and emotion. At the same time, ECG can be used to detect arrhythmia, myocardial injury and other diseases. In addition, bioelectrical instruments can also be used in psychological research, neuroscience, health management and other fields.

With the continuous progress of science and technology, bioelectrical instruments are also developing. In the past, bioelectrical instruments mainly used traditional wired signal transmission, but in recent years, with the development of wireless communication technology, wireless bioelectrical instruments began to be widely used. In the future, bioelectrical instruments will be more widely used, including the detection and diagnosis of specific diseases. At the same time, the development of bioelectrical instruments will make people know more about important organs such as brain and heart.
