%X Many methods have been considered for human larynx imaging and especially vocal-folds monitoring. A widely-used non-invasive technology for vocal-folds monitoring is electroglottography (EGG), a technology based on impedance measurement of the larynx. Electrical impedance tomography (EIT) is another non-invasive electrical measurement method which attempts to reconstruct the conductivity map inside an object. It has been used in several human monitoring applications, and a theoretical study of EIT for vocal-folds monitoring has given promising results but, to our knowledge, no device has been built. In our project, we aim at developing an innovative measurement system for vocal-folds monitoring using both EGG and EIT technologies. Two devices are currently under development. In this paper, we present a brief review of EGG and EIT technologies, the principles of the two new devices and the perspectives they offer for both medical and research fields.
