A study of forearm muscular activity measurement by layered sensors

Abstract

In this paper, simultaneous measurement of electromyogram (EMG), Mechanomyogram (MMG), and oxygen dynamics at the forearm is presented by the proposed sensor. The proposed sensor is a layered structure of a transparent thin electrode, a transparent piezo film and near-infrared sensor. EMG, MMG and oxygen dynamics are respectively measured by the electrodes, piezo film and near-infrared sensors. The three types of data are obtained by a pair of proposed sensors. In an experiment, simultaneous measurement of EMG, MMG and oxygen dynamics at the forearm was demonstrated using the proposed sensors. As a result, it was shown that simultaneous measurement of EMG, MMG and oxygen dynamics at the forearm was possible although measurement accuracy was insufficient. In addition, it is suggested that the proposed sensor has the potential for analysis of the muscular activity.
