Description
【Technical field】 [0001] The present invention relates to a biological electrode that contacts the skin of a living body and can detect physical conditions such as heart rate by using electrical signals from the skin, its manufacturing method, and a biological electrode composition suitable for the biological electrode. 【Background technique】 [0002] In recent years, with the spread of IoT (Internet of Things), the development of wearable devices is progressing. Clocks and eyeglasses that can be connected to the Internet are typical examples. In addition, wearable devices that can monitor the state of the body at any time are also required in the medical field and sports field, which will be a field with growth potential in the future. [0003] In the medical field, for example, some people study wearable devices that monitor the state of body organs by sensing weak currents, such as electrocardiography that uses electrical signals to sense heart beats. The measurement of...
