Development of a printed e-textile for the measurement of muscle activation via EMG for the purpose of gesture control

This paper details the development of an e-textile gesture controller using screen-printed electrodes to measure Electromyography (EMG); the electrical signals produced in a muscle during its use. The final e-textile consists of 7 fabric electrodes able to take measurements from three muscular groups in the right forearm. When accompanied with processing circuitry, also produced in this study, a total of five gestures are uniquely identified with an average accuracy of ~93% when operating with a switching delay of 150 ms or greater.
