Eligibility
Key inclusion criteria
A subject must meet all of the following inclusion criteria to be eligible for inclusion in this study:

* Age above 18 years not under guardianship, under curatorship or under judicial protection.
* Body Mass Index (BMI) < 35 kg/m2.
* OSA (15 < AHI < 80 events/h sleep) documented by a sleep study performed during the past 24 months in the absence of any major weight change or other medical issues.
* Subject must be eligible for a diagnostic DISE or surgical procedure (acute study measures only).
* Written informed consent obtained from the subject prior to performing any study specific procedure.
* Willing and capable to comply with all study requirements, including specific lifestyle considerations, evaluation procedures and questionnaires for the whole duration of the trial.

Key exclusion criteria
Subjects meeting any of the following criteria will be excluded from participation in this study:

* Major anatomical or functional abnormalities that would impair the ability of the electrode arrays to be positioned.
* Significant comorbidities that contraindicate surgery or general anesthesia/DISE
* Significant tongue weakness
* Any other chronic medical illness or condition that contraindicates a surgical procedure or general anesthesia/DISE in the judgment of the investigator.
* Prior surgery or treatments that could compromise the placement and effectiveness of the electrode array systems:

* Airway cancer surgery or radiation,
* Mandible or maxilla surgery in the previous 3 years (not counting dental treatments),
* Other upper airway surgery to remove obstructions related to OSA in the previous 3 months (e.g., uvulopalatopharyngoplasty (UPPP), tonsillectomy, nasal airway surgery),
* Prior hypoglossal nerve stimulation device implantation.
* Currently pregnant, or breastfeeding during the study period
