Italian physician L Galvani demonstrated the relationship between electricity and muscle contraction that occurs in the electric fluid carried to the muscles by the nerves. He coined the term animal electricity to describe the muscle-activating force. One hundred and fifty years after he determined that muscle activation is generated by an electric fluid carried by the nerves, mathematician N. Wiener studied an artificial hand controlled by an electrical current produced in the muscles. This book discusses new developments, procedures and applications of electromyography.

This book outlines the electro-activity in the human body, human behavior, and other bio-information during image viewing and applies it to a hygienic and clinical setting. The book begins by explaining the basic science of brain measurements and the endocrine system, before analyzing the bio-signals obtained from electrocardiogram (ECG), electrogastrography (EGG), electro-oculography (EOG) and much more. As the book subsequently demonstrates, these bio-signals can be measured using wearable devices, and the data can be used to detect undiagnosed diseases and health-relevant abnormalities....
