This research aims to use muscle stiffness as an alternative method to surface EMG in measuring subtle muscle movements. These measurements can be used as an input interface to devices like prosthetic limbs. In this paper, stiffness of the forearm muscle during gripping motion is measured using a piezoelectric haptic sensor. As a comparison the same test was performed using surface EMG. Results regarding the correlations of each method to gripping force are presented.
