Speech Recovery Device Through Electrotactile Stimulation Using FSR Technique

Abstract

The tongue is a significant muscle that helps with syllable articulation and swallowing. Patients with neurological injuries like cerebrovascular and many more related injuries possibly will have difficulty speaking and swallowing as a result of a loss in tongue control. Few attempts have been made in the past to measure tongue pressure and its spatial distribution. Many designs incorporated tubes or cables to connect the intraoral measurement equipment to the extra oral data collecting electronics, disrupting the tongue's and lips' natural functions. The main goal of the sensor system that is being developed is to decrease the patient's discomfort caused by the measuring incident. As a result, the intraoral device must have a data acquisition circuit. Sensors and electronics must be extremely small and precise. To rehabilitate the tongue, a perfect non-hazardous stimulation is required employing frequency and current controlled methods. Electro tactile stimulation is used to stimulate the tongue as part of the rehabilitation process. Electrical stimulation, i.e. electro tactile stimulation, is capable of activating the afferents below the surface which was stimulated, and thus lead to insight. Electrotactile Stimulation is most typically employed to provoke stimuli over the perceptual threshold, which is known as sensory substitution and augmentation.
