hitoeCap

Abstract

We present "hitoeCap", which has Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) textile electrodes for measuring electromyography (EMG) of the masticatory muscles. Masticatory muscle activity is relevant to several daily activities such as diet, sleep bruxism, and human motor control. Our aim is to leverage continuous EMG data of the masticatory muscles for monitoring daily activities. For motion artifact reduction, which is a major problem for measuring EMG with textile electrodes, we propose a new algorithm based on kinesiology by utilizing a correlation coefficient between the root mean square of the right side EMG and that of the left side EMG. We have developed a hitoeCap prototype and conducted experiments to verify the usability of the PEDOT-PSS electrodes and the feasibility of our proposed algorithm.
