Course description

To monitor eating, we attach dry electrodes on eyeglasses to measure EMG signals from Temporalis muscles. Due to head shape variation, dry electrodes usually face bad skin contact issue, which impairs EMG signal quality. The project aims at solving this problem by designing a mechanical model of dry electrodes with emphasis on selecting materials of suitable properties. This outcome of the project will be an eyeglasses prototype that can automatically fit electrodes to the wearer’s head.
