MyoWare – MYOELECTRIC SENSOR

Written by: Carolina Barrera Our muscles are controlled, and usually move thanks to electric impulses that produce contraction in these, and the reaction to that contraction is what we know as a movement. Electromyography technology was developed to evaluate and record this electrical activity. Myoelectric signals are becoming popular in medicine and prosthetic technology probably […]
