Future Indications

VNS for multiple indications is actively being studied by a global research community.


AI-Powered Vagus Nerve Stimulation

Transcutaneous auricular vagus nerve stimulation (taVNS) involves electrical stimulation of the vagus nerve at the cymba concha of the outer ear. This technique has proven to be a robust approach to neuromodulation, affecting aspects of cognition and well-being. 

Our patented solution leverages an AI/ML platform to personalize user experience through any REVAI-enabled TWS earbuds.
