Background

Bioelectricity is the electricity generated during the life of a living being. The main basis is the potential difference between the inside and outside of the cell membrane, i.e., the membrane potential. The membrane potential at rest is usually tens of millivolts, negative inside and positive outside, and is called "resting potential". When the cell membrane is damaged, the membrane potential is reduced or lost. When an excitable cell (such as a neuron or muscle cell) is stimulated to conduct an impulse, its membrane potential changes sharply, temporarily changing to negative inside and positive outside, called "action potential". The complex electrical changes of organs such as brain and heart are the sum of the electrical changes of their constituent cells. Electroencephalograms, electrocardiograms, electromyograms, and the like reflect the functional states of these organs, and are widely used in clinical diagnosis.
