Fig. 4From: A new flexible piezoelectric pressure sensor array for the noninvasive detection of laryngeal movement during swallowingRepresentative recordings obtained from a woman with an unclear laryngeal prominence during swallowing. A, B Same format as in Fig. 3B. Since a negative peak in sensor 5 (arrow a) occurred at around the same time as the first positive peak in sensor 4, the laryngeal prominence must have been positioned just under sensor 5 at the very beginning of the swallowing and moved in the direction of sensor 4Back to article page
