Effects of Vibratory and Thermal Stimuli During Mastication on the Sensation of Mastication
Keiichiro Yamamoto, Naohiro Fukumura (Toyohashi Univ. of Tech.) MBE2026-19
Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a system for modifying perceived chewing sensation by applying vibration and thermal stimuli during mastication. The system detects chewing using electromyographic signals from the masseter muscle and synchronizes the detected chewing with external sensory stimulation. An experiment was conducted using biscuits under five conditions: no device, device without stimulation, vibration stimulation, thermal stimulation, and combined vibration and thermal stimulation. Participants evaluated several sensory attributes, including hardness and chewiness, using a nine-point scale. The results showed significant differences among the five conditions in the overall evaluation of hardness and chewiness. These results suggest that synchronized sensory stimulation during mastication can alter the perceived texture of food.
