The tongue is an important muscle and contact with the hard palate during the articulation of a syllable or during swallowing is fundamental. Patients who have had cerebrovascular disorders or other neurological disorders may have speech problems and swallowing problems due to decreased ability to control the tongue. In this paper we describe a device with the aim of providing a noninvasive aid for rehabilitation. The proposed device has been designed with the purpose of measuring the pressure of the tongue on the palate directly in the oral cavity and transmitting the data wirelessly. The device is minimally invasive because no cable is used to connect the pressure sensor in the oral cavity with the reading unit placed on the outside. A first prototype was developed and preliminary data for the behavior of the sensor were made. A specific experimental setup has been designed and performed and a test protocol has been defined and adopted. The preliminary experimental results obtained show a wide measurement range, up to 100 kPa. The fields of application of this device are the treatment of people with swallowing or phonetic disorders.
