Outline of Final Research Achievements

sEMG (Surface Electromyography) is the electric activity of groups of muscles measured with electrodes on the skin surface. Since it reflects motion intentions, sEMG has been studied as a signal to control welfare machines. This study investigated the electrodes, measurement method, and selection of multi-channel sEMG signals. Soft and wearable sEMG electrodes were developed with conductive polymers and conductive silicon. The relation between bioelectric characteristics and the quality of sEMG was elucidated. And a multi-channel sEMG measurement system was developed and validated with healthy subjects and amputees.
